Zara Bagdasarian (UCB) "Solar Neutrinos with Borexino: First Evidence of CNO Fusion Cycle"
2020-07-16 16:00 - 17:00 UTC | Zoom Talk, 50A-5132, Berkeley, ca, 94720
Abstract:
The prime energy producer in the sun is the fusion of hydrogen to form
helium. However, there is more than one way for this fusion to take
place: for stars the size of the sun or smaller, the proton-proton (pp)
chain reactions dominate (~99%), while in heavier stars, the
carbon-nitrogen-oxygen (CNO) cycle is expected to play a more important
role. Not only these fusion reactions would not have been possible
without the emission of neutrinos, neutrinos are the only way to
directly access the processes in the core of the sun.
Borexino experiment, located at the Laboratori Nazionali del Gran Sasso,
was built with a primary goal of the Be7 solar neutrinos (part of pp
chain) detection. In more than a decade of data taking, Borexino has not
only demonstrated the unprecedentedly high sensitivity towards Be7 solar
neutrinos (<3%) but performed a comprehensive study of low-energy
neutrinos from the complete pp-chain. After a number of developments in
both hardware and software, Borexino presents the first experimental
evidence of the up-to-now elusive CNO fusion cycle in the Sun. The
absence of the CNO neutrinos signal is disfavoured by the Borexino
experiment at 5σ.

Kyle Dawson (U. Utah) "The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Cosmological Implications from two Decades of Spectroscopic Surveys at the Apache Point observatory"
2020-07-09 16:00 - 17:00 | 50-Auditorium
Abstract:
The Extended Baryon Oscillation Spectroscopic Survey (eBOSS) concluded observations of the cosmic distance scale and the growth of structure in February, 2019. The three dimensional clustering in all samples from the Sloan Digital Sky Survey (SDSS) was used to make 15 distinct, high precision measurements of Baryon Acoustic Oscillations (BAO) to an effective redshift z<2.4 and six measurements of redshift space distortions (RSD) to z<1.5. With this redshift coverage and sensitivity, the SDSS experiment is unparalleled in its ability to explore models of dark energy. Using available cosmological samples, we provide new constraints on the cosmological model with an emphasis on the role of the final BAO and RSD clustering measurements in advancing the cosmological model. In this talk, I will give a brief overview of the BAO and RSD measurements and present the highlights of the advances in modeling dark energy, the local expansion rate, tests of general relativity, neutrino masses, and the overall cosmological model.

Beate Heinemann (DESY) "European Strategy for Particle Physics Update 2020"
2020-06-25 12:00 - 13:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
Abstract:
I will present the updated European strategy for particle physics which was announced by the CERN Council in June. The strategy was developed in a process that spanned two years and engaged both the European and the international community of particle physics, as well as related scientific disciplines. The highest-priority physics recommendations are the study of the Higgs boson and the exploration of the high-energy frontier: two crucial and complementary ways to address the open questions in particle physics. Questions related to the dark universe, flavor and other puzzles of the Standard Model are also discussed. Finally, technological and societal challenges and opportunities are also highlighted.

Stephen Gourlay (LBNL) "Snowmass 2021: Survey of Potential Collider Options"
2020-06-11 16:00 - 17:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
ABSTRACT:

We are now approximately 3 months into the next Snowmass process and a plethora of ideas is starting to surface. Technical maturity of the proposed facilities ranges from shovel ready to those that are still largely conceptual. Developments in accelerator technology since the last Snowmass could increase the number of feasible ideas for P5 to consider. This talk will give a brief summary of some of the collider options; current status, technical readiness level and challenges, that we expect to see coming out of the current planning process.

Rakshya Khatiwada (Fermilab) "Hunting for Dark matter using quantum devices and sensors"
2020-06-04 16:00 - 17:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
Rakshya Khatiwada (Fermilab)
“Hunting for Dark matter using quantum devices and sensors”

Abstract:

Very few mysteries in our current picture of the universe are bigger than the puzzle of dark matter. Recently the QCD axion — a weakly interacting, sub-eV particle — has been in the limelight as a cold dark matter candidate which also enjoys compelling theoretical motivation as a possible solution to the strong CP problem. This talk will give an overview of modern axion searches with a detailed discussion of the role of quantum devices and technology in the most sensitive axion experiment to date. Furthermore, it will discuss promising novel methods of axion searches using quantum sensors as single photon counters that could make possible the investigation of axions in previously uncharted mass ranges.

Daniel Carney (U. Maryland) "Fundamental Physics at the Quantum Limits of Measurement
2020-05-26 16:00 - 17:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
Abstract:
40 years ago, Caves, Thorne, and their collaborators asked the question: what are the fundamental quantum limits on the measurement of a small position displacement? The answers to these conceptual questions led to the first direct detection of a gravitational wave by LIGO in 2016. I will review these types of quantum limits and discuss their application to particle physics. In particular, I will present some new dark matter detection ideas which leverage quantum sensing and control of massive opto-mechanical systems. Current experiments with these devices are already capable of ruling out some exotic dark matter candidates, and I will focus on these and their next-generation extensions. I will also present some much longer-term applications: a scheme for direct detection of heavy dark matter purely through gravity, and tabletop experiments testing the quantum nature of gravity.

Alex Kim (LBNL)"Opportunities for Peculiar Velocity Surveys Using DESI, ZTF-II, and the Vera C. Rubin Observatory"
2020-05-21 16:00 - 17:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
ABSTRACT:
The motions of galaxies on top of the Hubble expansion, peculiar velocities, are a probe of clustering and the growth of structure in the Universe. For distance indicators, peculiar velocities manifest themselves as residuals on the Hubble diagram. Ongoing and upcoming wide-field surveys measuring unprecedented numbers of distance indicators, together with improvements in the calibration of Type Ia supernova brightnesses, will provide exquisite precision in the mapping of the peculiar velocity field or more precisely the peculiar distance field. LBL is well positioned to make distance measurements of sources from DESI, the Zwicky Transient Facility (ZTF), ZTF-II, and the Rubin Observatory in order to produce compelling constraints on the laws of gravity responsible for the growth of structure.

Alexander Stibor (LBNL) "QIS with Coherent Electrons: Quantum Sensors, Superconducting Emitters, Signal Transmission and Decoherence Studies"
2020-05-19 16:00 - 17:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
Abstract:
Creating, manipulating and detecting coherent, entangled quantum states and isolating quantum systems from decoherence is at the heart of future quantum information science technologies. With the rise of novel instruments in quantum electronics, the coherent emission and control of free electron beams become relevant in various fields of physics. In this presentation, I will give an overview of the research performed in Tuebingen (Germany) and at the LBL Molecular Foundry where we are currently realizing the QUINTESSENCE QIS project. The aim is to use the matter-waves of electrons, superconductivity and correlation detection to develop novel quantum techniques and applications in sensor technology, electron microscopy and signal transmission. Such experiments are demonstrated with a biprism electron interferometer. We realized a correlation sensor for electromagnetic and vibrational perturbations and a secure signal transmission method by matter-wave modulation. Furthermore, I will present a characterization setup for a superconducting niobium nano-tip field emitter. This beam source has the potential to emit entangled electron pairs that open up new modes in quantum information, quantum metrology and electron spectroscopy. To achieve long coherence times in future quantum instrumentation, a basic understanding of decoherence, being the transition from a quantum to a classical state, is crucial. We studied experimentally the Coulomb-induced decoherence of electrons in a superposition state and were able to rule out three of four current theoretical approaches in the literature. It allows the development of novel non-invasive techniques for quantum electron microscopy.http://physics.lbl.gov/rpm/index.php/events/

Hitoshi Murayama (LBNL/UCB)"International Linear Collider"
2020-05-14 16:00 - 17:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
ABSTRACT:
Having discovered the Higgs boson without obvious new particles at the Large Hadron Collider, precision study of the Higgs boson at a Higgs factory is the obvious strategy at the energy frontier. I will review basic motivation and various options for the Higgs factory, and discuss ILC in this context. I will also discuss some recent political developments.

Ben Nachman (LBNL) "Modeling final state radiation on a quantum computer"
2020-05-12 16:00 - 17:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
Abstract:
Particles produced in high energy collisions that are charged under one of the fundamental forces will radiate proportionally to their charge, such as photon radiation from electrons in quantum electrodynamics. At sufficiently high energies, this radiation pattern is enhanced collinear to the initiating particle, resulting in a complex, many-body quantum system. Classical Markov Chain Monte Carlo simulation approaches work well to capture many of the salient features of the shower of radiation, but cannot capture all quantum effects. I will show how quantum algorithms are well-suited for describing the quantum properties of final state radiation. In particular, I will describe a polynomial time quantum final state shower that accurately models the effects of intermediate spin states similar to those present in high energy electroweak showers. The algorithm is explicitly demonstrated for a simplified quantum field theory on a quantum computer. One of the greatest challenges for current quantum computers is their significant noise. I will present new techniques for mitigating both readout noise and gate error noise. Readout errors are equivalent to detector effects in high energy physics (HEP) and I will show how building a bridge between fields can improve quantum computing in general, not only for HEP. For gate error mitigation, I have proposed a new technique that can achieve a better precision than existing methods with a significantly reduced quantum complexity. Finally, I will discuss future directions at the interface between quantum computing and high energy physics. See 1901.08148, 1904.03196, 1910.00129, and 2003.04941 for details.

RPM - Physics Division | Ben Nachman (LBNL) "Gearing up for the 2021 APS DPF Community Planning Process (aka Snowmass)" https://lbnl.zoom.us/j/95017728528
2020-04-30 16:00 - 17:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
Abstract:

The American Physical Society’s Division of Particles and Fields is gearing up for its next community planning process (for historical reasons, called Snowmass). This process will occur over the next year and culminate in a 10 year plan (with a 20 year vision) for the future. It is critical for us to provide input to this process, which will ultimately inform the funding agencies about our community’s priorities for the future. In this talk, I will briefly introduce the various frontiers of the 2021 Snowmass process and will then mostly focus on the Computational Frontier and its connection to the other frontiers. In particular, this is an interesting time for computation with significant big data tools and infrastructure being developed by the broader scientific and industrial communities and with the advent of new (not part of the last Snowmass!) technologies like deep learning and quantum computing.

How deadly is COVID-19? A time series analysis of Italy mortality data

Abstract:

A counterfactual analysis of 2020 mortality data reported from towns in Italy, with data from the previous five years as control, reveals a large excess of deaths in March 2020. The analysis shows a good agreement with reported COVID-19 mortality for age<70 years, but an excess in total mortality increasing with age above 70 years, suggesting there is a large population of predominantly old people missing from the official fatality statistics. We estimate that the number of COVID-19 deaths in Italy is 52,000 $pm$ 2000 as of April 18 2020, more than a factor of 2 higher than the official number. We determine infection fatality rate (IFR) lower bound of 0.84% for Lombardia and infection rate of 23% for Lombardia, a factor of 35 above the number of positive tests. The infection rate for Bergamo province is 63%, suggesting herd immunity has been reached there. The analysis can help predict corresponding numbers in USA: we predict 0.5% lower bound on IFR for NYC and Santa Clara county. We observe that the COVID-19 mortality tracks closely the overall mortality of the underlying population, explaining why we see so many more deaths below age of 65 as a fraction of total in NYC relative to Italy.

Rodrigo Alonso (Durham U) "Geometry for Higgs Dynamics and Effective Field Theory"
2020-04-09 12:00 - 13:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
Abstract:

The three Nambu-Goldstone bosons in the longitudinal modes of the W and Z together with the Higgs boson span a 4-dimensional manifold. The geometry of this manifold, invariant under field re-parametrization, encodes the scalar dynamics which are vastly unexplored at present. The small but finite curvature limit recovers the Standard Model and corrections in its effective field theory. First order corrections in this framework encode widely different physics and serve to test and constrast the different facets of the SM and their correlation.

Lina Necib (Caltech) "Dark Matter in the Era of Gaia"
2020-04-02 16:00 - 17:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
ABSTRACT:
The Gaia mission has provided distance and velocity measurements of over a billion stars in the Milky Way, making it the largest stellar catalog at hand. Simultaneously, recent developments in cosmological simulations have made it possible to track stars and dark matter in realistic Milky Way-like galaxies. In this talk, I will demonstrate how using cutting-edge simulations and Gaia data in tandem has enabled me to start building the first local map of the cold dark matter phase space distribution in our Galaxy. Doing so led me to discover Nyx, a stream of stars in the solar neighborhood that I identified using machine learning methods. Nyx, potentially the result of a prograde merger, is crucial in understanding the formation of the disk of the Milky Way as it might have been associated with an accreted dark disk. Finally, I will summarize how future surveys will help fully map out the phase space distribution of dark matter in the Milky Way, and show that such an empirical map will have extensive ramifications for dark matter searches.

Adi Ashkenazi (Fermilab) "Probing V Interactions for V Physics"
2020-03-31 16:00 - 17:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
Abstract:

The ability of current and next generation accelerator based neutrino oscillation measurements to reach their desired sensitivity requires a high-level of understanding of the neutrino-nucleus interactions. These include precise estimation of the relevant cross sections and the reconstruction of the incident neutrino energy from the measured final state particles. Incomplete understanding of these interactions can skew the reconstructed neutrino spectrum and thereby bias the extraction of fundamental oscillation parameters and searches for new physics. In this talk I will present the first exclusive differential cross section measurement using neutrino-Argon Quasi Elastic like interactions from the MicroBooNE experiment. In addition, using wide phase-space electron scattering data, collected using the CLAS spectrometer at the Thomas Jefferson National Accelerator Facility (JLab), the reconstruction of the incoming lepton energy from the measured final state is being tested. Disagreements with current event generators, used in the analysis of neutrino oscillation measurements, are observed which indicate underestimation of nuclear effects. The impact of these findings on bias in oscillation analyses will be discussed.

Richard Bonventre (LBNL) "Searching for Muon to Electron Conversion: The Mu2e Experiment at Fermilab"
2020-03-26 16:00 - 17:00 | 50-Auditorium
Abstract:
The Mu2e experiment will search for the charged lepton flavor violating (CLFV) neutrino-less conversion of a negative muon into an electron in the field of a nucleus, reaching a 90% C.L. limit of 8×10^-17 on the conversion rate. This sensitivity is a four-orders of magnitude improvement over previous experiments, and allows Mu2e to probe new physics at mass scales up to 10^4 TeV, far beyond the direct reach of colliders. Mu2e is currently under construction at Fermilab, and expects to begin data taking in 2023. In this talk I will present the current status of the experiment. I will also discuss the development of Mu2e detector simulations as well as the results and impact of prototype data analyses.

Christopher Marshall (LBNL) "The Dawn of DUNE: Neutrino Oscillations in the Precision Era"
2020-03-24 16:00 - 17:00 | 50-Auditorium
ABSTRACT:
Neutrino oscillation is a well-established phenomenon. Over the past two decades, nearly all of the parameters governing these oscillations have been measured experimentally, using neutrinos from the atmosphere, the sun, nuclear reactors, and particle accelerators. The remaining unknowns have very interesting consequences but are challenging to access experimentally as they require high-precision measurements. The Deep Underground Neutrino Experiment (DUNE) will be sensitive to these unknowns, including whether neutrinos violate CP symmetry, which could be the key to understanding why the universe is matter-dominated. Constraining systematic uncertainties is critical for DUNE to reach its physics goals, and requires a highly-capable near detector. I will present the discovery potential of DUNE and discuss how the experiment is designed to address the many challenges of precision neutrino oscillation physics. I will give particular focus to how the near detector can mitigate large uncertainties on the neutrino flux prediction and interaction cross sections.

Masha Baryakhtar (NYU) " New Physics Across the Spectra"
2020-03-19 16:00 - 17:00
ABSTRACT:
Theories beyond the Standard Model of particle physics often predict new, light, feebly interacting particles whose discovery requires novel search strategies. A light particle, the QCD axion, elegantly solves the outstanding strong-CP problem of the Standard Model; cousins of the QCD axion can also appear, and are natural dark matter candidates. First, I will discuss my experimental proposal based on thin films, in which dark matter can efficiently convert to detectable single photons. A prototype experiment is underway, and current techniques promise to reach significant new dark matter parameter space.
Second, I will show how rotating black holes turn into axionic beacons. When an axion’s Compton wavelength is comparable to a black hole size, energy and angular momentum from the black hole source exponentially-growing bound states of particles. I will discuss new results on axion interactions, including new dynamics in the bound states, and show how black holes populate the universe with axion waves that can be detected in future laboratory searches.

Daniel Ruterbories (Rochester U) "Electroweak Probes of the Nucleus and the Era of Precision Neutrino Physics"
2020-03-17 16:00 - 17:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
ABSTRACT:
Neutrino oscillation experiments such as NOvA and T2K search for the disappearance and appearance of muon and electron flavor neutrinos in a predominately muon-type beam. These experiments are currently measuring the oscillation parameters to greater precision but will not be able to measure the CP phase with enough significance to pin down CP violation in the lepton sector. The next generation of experiments, DUNE and Hyper-Kamiokande, will push the field into its precision era, requiring precise predictions of the flux and neutrino interactions used to measure CP violation.
The MINERvA experiment is a dedicated neutrino interaction experiment set in the NuMI beamline at Fermi National Accelerator Laboratory. The purpose of the experiment is to measure neutrino interactions off a variety of nuclear targets to probe nuclear effects and inform modeling of neutrino interactions. The experiment measures interactions over a wide range of Q2 and W kinematics. These including interactions in the quasi-elastic, resonant, and shallow to deep inelastic scattering regions. The experiment has run with two beam energies peaked at ~3 and 6 GeV in both neutrino and anti-neutrino enhanced modes.
In this seminar, I will describe the current state of neutrino-nucleus interaction physics and how MINERvA data will inform future experiments. Specifically, I will describe the extensive tuning exercise MINERvA has done to describe interactions in the quasi-elastic into the resonant pion regions of kinematic phase space. I will also discuss lessons learned and describe some of the next generation measurements necessary to prepare for the DUNE experiment.

Ka Vang Tsang (SLAC) "Imaging Neutrinos: Machine Learning in LArTPC"
2020-03-12 16:00 - 17:00 | 50-Auditorium
Abstract:

Ever since the discovery, neutrinos have proven to be one of the most intriguing subatomic particles. In the past two decades, we have made tremendous progress in the establishment of the neutrino oscillation phenomenon. We are now able to reveal the nature using neutrinos, such as CP violation in the lepton sector, the neutrino mass hierarchy, and the possible existence of the sterile neutrinos.
Liquid argon time projection chamber (LArTPC) is a novel technology for neutrino detection because of its excellent imaging capability of charged particles. However, it is challenging to reconstruct and analyze LArTPC events efficiently in large scale detectors. In this talk, I will review some revolutionary ideas in machine learning, and demonstrate the use of these techniques to tackle the challenge in LArTPC event reconstruction.

Keisuke Harigaya (IAS) “ Physics beyond the standard model from Higgs Parity”
2020-03-10 16:00 - 17:00 | HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585, 50A-5132
Abstract:

The discovery of the Higgs boson has revealed that the quartic Higgs self-coupling becomes small at very high energy scales. Guided by this observation, I introduce Higgs Parity, which is a spontaneously broken symmetry exchanging the standard model Higgs with its parity partner. In addition to explaining the small Higgs quartic coupling, Higgs Parity can provide a dark matter candidate, solve the strong CP problem, and arise from an SO(10) grand unified gauge symmetry. I will show that the Higgs Parity symmetry breaking scale is determined by standard model parameters and predicts experimental signals such as the dark matter direct detection rate and the proton decay rate. As a result, Higgs Parity provides a tight correlation between future precision measurements of standard model parameters and these experimental signals

Tom Melia (Kavli IPMU - Japan)“ 'CMB-ing' the Search for New Physics at Colliders"
2020-03-05 16:00 - 17:00 | 70A-3377, 70A-3377
Abstract:

The effect of dark matter and dark energy in the universe can be inferred through measurements of anisotropies in the cosmic microwave background (CMB). The quantum effect of new physics on collisions at the Large Hadron Collider can be similarly inferred through measurements of what could be considered “anisotropies” in standard model processes. But how precise can one make the analogy? For example, does it make sense to talk of a “power spectrum of the standard model”? In this talk I will show how to construct just such a power spectrum, via a solution to a long-standing problem in effective field theory, and a hidden geometry in Fermi’s Golden Rule.

David Caratelli (Fermilab) "Neutrinos at Short Baselines: the MicroBooNE Experiment"
2020-03-02 16:00 - 17:00 | HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585, 50A-5132
Abstract:

While neutrino oscillation physics has entered an era of precision measurements, several anomalies in experiments at short baselines remain without a satisfactory answer.

The MicroBooNE experiment has been recording neutrino interactions on Fermilab’s Booster Neutrino Beam since 2015 employing a liquid argon TPC detector. This talk will present recent progress on MicroBooNE’s measurement of electron neutrinos aimed at addressing past anomalies observed by the MiniBooNE collaboration.

Finally, I will talk about how developments in the ability to use liquid argon TPC detectors in the sub-GeV regime can open new opportunities in neutrino and rare-event physics with Fermilab’s upcoming short- and long-baseline neutrino programs.

Ken Van Tilburg (NYU/IAS) "The Structure of Dark Matter on Small Scales"
2020-02-27 16:00 - 17:00 | Zoom Talk, 50A-5132, Berkeley, ca, 94720
ABSTRACT:

Halometry—mapping out the spectrum, location, and kinematics of nonluminous structures inside the Galactic halo—can be realized via effects that variable weak gravitational lensing induces on the proper motions of stars and other luminous background sources. Modern astrometric surveys provide unprecedented positional precision along with a leap in the number of cataloged objects. Astrometry thus offers a new and sensitive probe of collapsed dark matter structures over a wide mass range, from one millionth to several million solar masses. It opens up a window into the spectrum of primordial density fluctuations with very small comoving wavenumbers, scales hitherto poorly constrained.

I will outline a program of detection strategies for dark matter substructure based on time-domain weak gravitational lensing, after summarizing existing techniques and constraints. I will present first results from analyses based on Gaia’s second data release. Finally, I will show that minimal models of axion-like dark matter naturally produce dense small-scale structures which can probed by the aforementioned astrometric lensing techniques.

Raquel Castillo Fernandez (Fermilab) "Searching for Nu Physics with High Resolution Detectors"
2020-02-25 16:00 - 17:00 | HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585, 50A-5132
Abstract:

Neutrino physics aims to answer some of the most pressing questions in particle physics: why the Universe is dominated by matter, why the neutrino mass is so small and if there are more types of neutrinos. Due to the neutrino’s weakly interacting nature and the complexity of their interactions, this research requires very large detectors able to identify low energy particles. This challenge has pushed the development of new technologies, such as the liquid argon time projection chamber (LArTPC) detectors, allowing for unprecedented precision in particle reconstruction, and to expand the scientific program searching for more rare channels are present in some theories of new physics beyond the current standard model. After briefly reviewing the basis of neutrino physics, I will introduce the main principles of the LArTPC detectors and how they can help us addressing some of the most relevant questions in particle physics. I will also describe the scientific achievements and the potential of the LArTPC neutrino program in the U.S., the current short (MicroBooNE/SBN) and the future long-baseline (DUNE) neutrino experiments.
