SUMMARY:Simon Knapen (IAS) "The Soft Frontier in Dark Matter Direct Detection"
DESCRIPTION:ABSTRACT:\nSearches for high energy signatures from beyond the standard model physics have advanced greatly\, but a lot of ground remains to be covered for soft\, low energy signals. In the context of dark matter direct detection\, future single-phonon detectors will be sensitive to dark matter with a mass as low as roughly 10 keV. In this regime\, the conventional nuclear recoil picture no longer applies and new theoretical tools are needed to correctly calculate the scattering rate. I will discuss the prospects for detector concepts based on superfluid helium and polar material targets\, where in the latter case we find a large daily modulation of the scattering rate.

SUMMARY:Dean Robinson (UCSC/LBNL) " Model-Independent Pathways to New Physics"
DESCRIPTION:ABSTRACT:\nNew methods and novel strategies are needed in the search for physics beyond the Standard Model (BSM). Motivated by signals of lepton flavor universality violation in semileptonic B decays\, I’ll discuss state-of-the-art theoretical developments and new model-independent theoretical tools that are required to self-consistently and efficiently classify these\, or other\, potential BSM effects within experimental analysis frameworks. I’ll then discuss the development\, theory motivations and reach for a proposed subdetector at the LHCb experiment — CODEX-b — capable of competitively searching for decays-in-flight of exotic long-lived particles\, which can be signals of a wide range of well-motivated BSM theories.

SUMMARY:Richard Bonventre (LBNL) "Investigating Lepton Flavor and Number Violation with the Mu2e and SNO+ Experiments"
DESCRIPTION:Abstract: \nNeutrino oscillation measurements have shown that lepton flavor is not conserved\, and that the standard model must be extended to include neutrino mass. Neutrino-less double beta decay measurements will help understand the nature and origin of neutrino mass\, while searches for charged lepton flavor violation will probe whether there is additional flavor-related physics beyond the standard model.\nThe SNO+ experiment will employ 780 tons of liquid scintillator loaded with 1.3 tons of 130Te for a low-background and high-isotope-mass search for neutrino-less double beta decay. SNO+ will run in multiple phases with different target materials\, allowing it to additionally study geo- and reactor neutrinos\, solar neutrinos\, and search for invisible modes of nucleon decay. First results from the SNO+ water phase will be presented. 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. Mu2e will improve the previous measurement by four orders of magnitude\, reaching a 90% C.L. sensitivity to CLFV conversion rates of 8 × 10−17 or larger. The experiment is sensitive to a wide range of new physics at high mass scales\, complementing direct searches at colliders. Mu2e is under design and construction at the Muon Campus of Fermilab; we expect to start taking physics data in 2023.

SUMMARY:Miaoyuan Liu (Fermilab) ""Measure what is measurable and make measurable what is not so — Uncover new physics with bosons at the LHC and upgrades of the CMS detector to maximize the discovery potential""
DESCRIPTION:Abstract:\n\nThe Standard Model describes the building blocks of matter and their interactions. It has been tested extensively with experimental data and found to be incredibly successful in describing nature. Discovering the Higgs boson in 2012 at the LHC completed the picture of the SM. The LHC is at the forefront of directly searching for new physics which is Beyond-Standard-Model (BSM)\, and I will discuss searches for supersymmetric partners of the electroweak bosons\, as well as measurement of an extremely rare process with three WWW bosons as stringent tests of the SM. I will also discuss the instrumentation which enables such studies. The discussion includes the recently completed CMS Phase-1 pixel upgrade\, as well as the R&D studies towards solving the future trigger and computing challenges using innovative machine learning approaches in future high energy experiments.

SUMMARY:Florian Beutler (U. Portsmouth) "Exploring Fundamental Physics with Galaxy Redshift Surveys"
DESCRIPTION:Abstract: \nIn this talk\, I will present various ways in which we can use galaxy redshift surveys to constrain fundamental physical models. This year the DESI experiment will launch\, collecting a dataset of about 50 million galaxies and Quasars. Using observables like Baryon Acoustic Oscillations and Redshift-space distortions we can use this dataset to measure the sum of the neutrino masses and the number of neutrino species as well as test models of dark energy and modified gravity. Moreover\, we can test models of the very early Universe (inflation) through primordial non-Gaussianity and primordial oscillations. The multitude of upcoming survey experiments (LSST\, Euclid\, WFIRST\, DESI) offers exciting prospects to put the standard model of cosmology (LCDM) to the test.

SUMMARY:Hitoshi Murayama (UCB/LBNL) "When a Symmetry Breaks"
DESCRIPTION:ABSTRACT:\n \nWhat is common among a magnet\, a halibut\, a rack of laundry\, your heart on the left of your body\, and the Higgs boson? The concept of spontaneous symmetry breaking is ubiquitous among many natural phenomena. I’ll describe the basic concept and its applications. In particular\, the original concepts from Anderson\, Nambu\, Goldstone\, and Higgs do not quite work in many systems that include a magnet on your fridge. I generalize the concept so that it is applicable to all known natural phenomena around us. I will also touch on recent related ideas on dark matter and dark energy.\n\nVideo:\nhttps://physicstalks.lbl.gov/2019/misc/HitoshiMurayama.html

SUMMARY:Gilbert Holder (U. Illinois\, Urbana-Champaign) "Particle Physics & Astrophysics with Wide Field mm-Wave Surveys"
DESCRIPTION:Abstract: \nThere have now been several generations of wide-field mm-wave surveys\, with several ongoing and upcoming very ambitious projects. We have already learned a great deal about the early universe and put strong constraints on particle physics extensions to the standard model\, also collecting large catalogs of strong gravitational lens systems and massive clusters of galaxies\, and learning a great deal about the growth of large scale structure in the universe. Ongoing and future experiments will continue to probe the early universe\, collect larger catalogs of interesting lenses and clusters\, and more carefully chart large scale structure\, while also opening new windows on solar system science\, transient events\, and multi messenger astronomy. These surveys are more widely known as “cosmic microwave background experiments.”

SUMMARY:Tomasz Skwarnicki (Syracuse) "Observation of New Pentaquark States and Other Exotic Hadrons"
DESCRIPTION:ABSTRACT:\nThe LHCb experiment has just discovered new narrow pentaquark states decaying to J/psi p\, which shed more light into the nature of the J/psi p structures reported by LHCb in Lambda_b decays four years ago. We will describe these results in a broader context of experimental evidence for multiquark states with more than minimal quark content. Future experimental prospects will be outlined.

SUMMARY:Paula Alvarez Cartelle (Imperial College London) “Search for lepton flavour universality violation in B+→K+ℓ+ℓ− decays at LHCb”
DESCRIPTION:Abstract:\n“Recent measurements of observables involving the flavour changing neutral current transition b→sμ+μ− have shown an interesting pattern of tensions with respect to the predictions of the Standard Model (SM). However\, the interpretation of these results is limited by our present understanding of the hadronic uncertainties affecting these predictions. Given the lepton-flavour-universal nature of the SM\, observables such as RK=BR(B+→K+μ+μ−)/BR(B+→K+e+e−)\, so-called Lepton Flavour Universality ratios\, profit from large cancellation of the theory uncertainties and provide a very sensitive probe for physics beyond the SM.\nThe previous measurement of the ratio RK performed by the LHCb collaboration\, using Run 1 data\, found a value compatible with the SM expectation at the 2.6σ level. In this seminar\, a new measurement of RK at the LHCb experiment will be presented. The new measurement reanalyses the data recorded by LHCb during Run 1\, and adds data collected during 2015 and 2016. The total dataset is double the size of that previously analysed.”

SUMMARY:Nathan Jurek (U. Oxford) "Observation of CP violation in charm decays (and more charming topics)"
DESCRIPTION:Precision measurements of the violation of charge-parity (CP) symmetry are crucial for testing the Standard Model and are sensitive probes for new physics contributions. While CP violation has been well-established by several different experiments in the decays of mesons containing strange and bottom quarks\, searches for CP violation in the decays of charm mesons had until recently come up empty-handed. Thanks to its unprecedentedly large samples of charm mesons\, the LHCb collaboration has succeeded in observing CP violation in the charm sector for the first time via a time-integrated analysis of D0→K−K+ and D0→π−π+ decays. These results will be presented\, along with recent time-dependent measurements which help constrain additional sources of CP violation in neutral charm mesons. Finally\, projections of future prospects in charm physics will be given.

SUMMARY:Daniel Santos (LPSC) "Directional Direct Dark Matter Detection and Neutrino Spectroscopy with MIMAC"
DESCRIPTION:ABSTRACT:\n \nThe hypothesis of the existence of non-baryonic dark matter in our galactic halo is supported by all astrophysical observations performed from cosmological to local scales. The measurement of one clear experimental signal of this matter represents one of the most important challenges for physics today. The direct detection of an elastic collision with a target nucleus of a weakly interacting massive particle (WIMP)\, the most accepted candidate for such a matter\, has to be discriminated from those produced by neutrons and neutrinos\, which produce the same expected signal. The only non-ambiguous signature to be able to discriminate the WIMP events from neutrons-induced events is to correlate these elastic collisions in the detector with the relative motion of our Solar system with respect to the galactic halo. The measurement of thedirection of the nuclear recoil track in 3D of a few tens of keV is called “directional detection”. The directional detection opens a new field in cosmology: it brings the possibility to build a map of nuclear recoils exploring the galactic halo and gives access to a particle characterization of dark matter. The MIMAC (MIcro-tpc MAtrix of Chambers) collaboration has developed in the last years an original prototype detector based on the direct coupling of a pixelized Micromegas with a special developed fast self-triggered electronics showing the feasibility of a new generation of directional detectors. The flexibility of the MIMAC detector to change the nucleus target\, changing its mass and spin\, makes possible to adapt the search of candidates proposed by the large mass direct detection projects as LUX\, Xenon1T\, SCDMS or Edelweiss. In the next years\, these large mass detectors will either detect some candidates or the neutrino background floor will limit them. In both cases a directional detector will be needed to confirm the galactic halo origin of such candidates or to go further the neutrino background. The MIMAC angular resolution measured coupling one of the chambers with COMIMAC\, a dedicated facility developed allowing ionization quenching factor measurements and electron calibration\, will be shown. The localization of the 3D track by the cathode signal will be described and the new possibilities open by this new directional detector in the neutron spectroscopy will be illustrated.\n \n

SUMMARY:Tucker Elliott (UCSD) "Characterization of Multiplexed Transition Edge Sensor Bolometers for the POLARBEAR-2 Cosmic Microwave Background Experiment"
DESCRIPTION:ABSTRACT:\nMeasurements of the Cosmic Microwave Background (CMB) temperature anisotropies and E-mode polarization have proven to be essential to our understanding of early universe cosmology by providing independent and strong evidence in favor of the Lambda-CDM cosmological model. However\, there is still untapped information in the CMB. Current-generation CMB experiments aim to measure the very faint B-mode polarization signal in order to find evidence of cosmic inflation and to measure the sum of the neutrino masses.\nPOLARBEAR-2 (PB-2) is a CMB polarization experiment located in northern Chile’s Atacama Desert at an altitude of 5\,200 meters. PB-2 is currently operating with over 7\,500 superconducting Transition Edge Sensor (TES) bolometers with a scheduled increase to over 22\,000 TES bolometers in the next year. PB-2 uses Digital Frequency Division Multiplexed (DfMux) readout to combine the bias and readout lines for sets of forty detectors onto a single pair of conductors in order to reduce cost and cryogenic complexity.\nSuperconducting (TES) bolometers are the gold-standard technology for observing the CMB because they can be used to make photon noise limited measurements. This is why CMB experiments continue to increase their detector counts – to achieve higher sensitivity. However in order to achieve optimal sensitivity\, the TES and multiplexing system must meet certain specifications. In this talk\, I will describe the requirements imposed on the detectors and readout system and the measurements I have performed at the University of California San Diego to characterize the detectors and readout system of the first and second PB-2 cryogenic receivers.

SUMMARY:David Stuart (UCSB) "Charged particle timing with 30-50 ps resolution in CMS for the high luminosity LHC upgrade"
DESCRIPTION:ABSTRACT:\nThe CMS detector is being upgraded for the phase two of the LHC\, where a dataset with much larger integrated luminosity will precisely measure the Higgs boson couplings and extend new phenomena searches to cover challenging scenarios with large backgrounds. Collecting that larger dataset will require much higher instantaneous luminosity causing up to 200 additional proton-proton collisions in each crossing which complicate event reconstruction. A new detector system within this upgrade\, the MIP Timing Detector\, will provide precise time measurements with 30 to 50 ps resolution for each charged particle. This 4D tracking will resolve the collisions in both space and time\, broadly improving the event reconstruction performance. I will describe the motivations for this new detector\, its design\, and recent progress.

SUMMARY:Barbara Jacak (LBNL/UCB) "The Mysteries of QCD Matter - Hot and Cold"
DESCRIPTION:ABSTRACT:\nQCD predicts a phase transition to quark gluon plasma. This plasma is now produced regularly in collisions of heavy nuclei at both RHIC and the LHC\, and it exhibits remarkable properties. Its vanishingly small shear viscosity to entropy density ratio means that it flows essentially without internal friction\, making it one of the most “perfect” liquids known. Quark gluon plasma is also very opaque to transiting strongly interacting particles. Determining the transport properties of quark gluon plasma is a key goal of current research\, and jets of hadrons offer a promising probe. Howevere\, it remains a mystery how this plasma emerges from cold\, dense gluonic matter deep inside nuclei within 1 fm/c. Furthermore\, properties of the cold QCD matter deep inside nuclei are unknown. I will discuss how a future electron-ion collider can help address these questions.

SUMMARY:Bruno Lenzi (IRFU\, Saclay France)"Recent results of the CMS experiment at LHC"
DESCRIPTION:Abstract:\nThe CMS experiment has analyzed up to 140 fb-1 of pp collisions delivered by the LHC at 13 TeV. This data has allowed for improved precision in several aspects of Higgs-boson and electroweak physics and pushed the frontiers on searches for new resonances\, long-lived particles and other phenomena. I will highlight some of the recent CMS results and prospects for the High-Luminosity running phase.

SUMMARY:Susan Hubbard (ESA\, LBNL) "Imaging Watershed Behavior &  Overview of the Earth and Environmental Sciences Area"
DESCRIPTION:ABSTRACT: \nQuantifying how terrestrial systems respond to climate change and other perturbations is challenging due to the complexity of associated processes that occur from bedrock-to-canopy and from genome to watershed scales. This presentation will describe the development of several new approaches to help bridge these compartments and scales through integrating disparate geophysical\, hydrological\, geochemical and microbial datasets. A brief overview of the Earth and Environmental Sciences Area will first be provided to motivate the technical presentation. The presentation will subsequently describe the use of new geophysical characterization approaches in an Arctic tundra ecosystem\, where increasing temperatures are thawing the permafrost\, potentially leading to significantly increased production of greenhouse gasses. The development and testing of new methods to quantify the structure and function of a mountainous watershed in the Upper Colorado River Basin\, where droughts and early snowmelt may influence downgradient water availability and water quality\, will then be presented. The recent advances are leading to insights about how these systems function and respond to perturbations – from local scales where native processes occur toward watershed scales that are relevant for managing natural resources.

SUMMARY:Patrick de Perio (Triumf) " CP Violation in Neutrino Oscillations with Hyper-Kamiokande
DESCRIPTION:Abstract: We live in a matter dominated world\, so where did all the antimatter go? The Hyper-Kamiokande (Hyper-K) experiment in Japan is trying to detect charge-parity violation (CPV) in neutrino oscillation\, which could help explain this phenomenon. As the successor of the T2K experiment\, Hyper-K produces a beam of neutrinos or antineutrinos directed towards a far detector 295 km away\, which is about 8 times bigger than the current far detector\, Super-Kamiokande\, a water Cherenkov detector. With an expected statistical uncertainty of 3% for both neutrinos and antineutrinos\, Hyper-K aims to tease out the small neutrino/antineutrino oscillation difference. In this talk\, I will discuss our efforts to control systematic errors at an unprecedented level\, arising from 1) neutrino beam production\, 2) neutrino interaction modeling\, and 3) water Cherenkov detector calibration.

SUMMARY:David Shih (Rutgers/LBNL) "Searching for the Unexpected at the LHC with Unsupervised Machine Learning"
DESCRIPTION:ABSTRACT: \nConventional methods for searching for new physics at the LHC have mostly been “top-down”: starting from a specific model\, searches are designed and optimized to have the best sensitivity to that model. Despite hundreds of conventional new physics searches at the LHC\, none have turned up any hint of new physics. Maybe it’s time to admit that we don’t know what we’re looking for. \nBreakthroughs in modern deep learning have the potential to revolutionize how we search for new physics at the LHC. In particular\, techniques borrowed from unsupervised machine learning could enable us to search for new physics in a largely model-agnostic way. In this talk I will review some promising recent proposals in this direction. These proposed search strategies could complement more conventional methods by finding surprising signals that were not anticipated by any model\, ensuring that we leave no stone unturned in the hunt for new physics at the LHC.

SUMMARY:Koji Terashi (CERN) " Quantum Computing and Possible Application to High-Energy Physics"
DESCRIPTION:Abstract: \nHigh-energy frontier in particle physics is going to enter into an era of precision studies after Run 3 at the LHC\, with the increase of proton luminosity and upgraded detectors. This will pose a significant challenge to the event reconstruction and data analysis\, where one has to look for (tiny) hints of new physics in a huge amount of collected data. Over the last few years quantum computing\, in particular the hardware systems with superconducting qubits\, has grown significantly\, making a quantum computer with order of 50-100 qubits\, called NISQ device\, nearly in hand. This motivates an exploration of this new technology in high energy physics (HEP) experiments\, aiming to identify interesting application of quantum algorithms to data analysis. In this talk\, I will discuss about possible HEP applications of quantum computing and current status of those studies. \n

SUMMARY:Zhaodi Pan (U. Chicago) "Instrument and science for the SPT-3G cosmic microwave background receiver"
DESCRIPTION:Abstract:\n\nSPT-3G is a third-generation camera for the 10-meter diameter South Pole Telescope (SPT)\, which is designed to measure the cosmic microwave background (CMB). To achieve a high mapping speed\, we have developed a new multichroic receiver with a total of 16\,000 polarization-sensitive detectors. SPT-3G began a 6-year 1500 square degree survey in February 2018\, which will produce measurements of CMB temperature and polarization anisotropies with an unprecedented combination of angular resolution and sensitivity. In this talk\, I will summarize the instrument status and highlight the development of the most compact millimeter-wavelength Fourier transform spectrometer\, which was used for SPT-3G and is also a prototype for the proposed PIXIE satellite. I will also discuss the science goals and current data analyses\, with a focus on the gravitational lensing analysis using SPT-3G’s first-year data.\n
