SUMMARY:David Caratelli (Fermilab) "Neutrinos at Short Baselines: the MicroBooNE Experiment"
DESCRIPTION:Abstract: \n\nWhile neutrino oscillation physics has entered an era of precision measurements\, several anomalies in experiments at short baselines remain without a satisfactory answer.\n\nThe 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.\n\nFinally\, 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.\n

SUMMARY:Richard Bonventre (LBNL) "Searching for Muon to Electron Conversion: The Mu2e Experiment at Fermilab"
DESCRIPTION:Abstract: \n \nThe 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.\n

SUMMARY:Tom Melia (Kavli IPMU - Japan)“ 'CMB-ing' the Search for New Physics at Colliders"
DESCRIPTION:Abstract:\n\nThe 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.

SUMMARY:Keisuke Harigaya (IAS) “ Physics beyond the standard model from Higgs Parity”
DESCRIPTION:Abstract: \n\nThe 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

SUMMARY:Ka Vang Tsang (SLAC) "Imaging Neutrinos: Machine Learning in LArTPC"
DESCRIPTION:Abstract:\n\nEver 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.\nLiquid 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.

SUMMARY:Daniel Ruterbories (Rochester U) "Electroweak Probes of the Nucleus and the Era of Precision Neutrino Physics"
DESCRIPTION:ABSTRACT: \nNeutrino 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. \nThe 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. \nIn 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. \n  \n\n──────────\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/372309777 \nMeeting ID: 372 309 777 \nOne tap mobile\n+16699006833\,\,372309777# US (San Jose)\n+13462487799\,\,372309777# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 646 558 8656 US (New York)\n+1 253 215 8782 US\n+1 301 715 8592 US\n+1 312 626 6799 US (Chicago)\nMeeting ID: 372 309 777\nFind your local number: https://lbnl.zoom.us/u/acBxMxIpwT \nJoin by SIP\n372309777@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n221.122.88.195 (China)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n209.9.211.110 (Hong Kong)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 372 309 777 \n──────────

SUMMARY:Masha Baryakhtar (NYU) " New Physics Across the Spectra"
DESCRIPTION:ABSTRACT: \nTheories 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. \nSecond\, 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.

SUMMARY:Christopher Marshall (LBNL) "The Dawn of DUNE: Neutrino Oscillations in the Precision Era"
DESCRIPTION:ABSTRACT: \nNeutrino 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. \n  \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/429952456 \nMeeting ID: 429 952 456 \nOne tap mobile\n+16699006833\,\,429952456# US (San Jose)\n+13462487799\,\,429952456# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US\n+1 301 715 8592 US\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 429 952 456\nFind your local number: https://lbnl.zoom.us/u/acBxMxIpwT \nJoin by SIP\n429952456@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n221.122.88.195 (China)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n209.9.211.110 (Hong Kong)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 429 952 456 \n──────────

SUMMARY:Adi Ashkenazi (Fermilab) "Probing V Interactions for V Physics"
DESCRIPTION:Abstract:\n\nThe 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.\n\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/415426450 \nMeeting ID: 415 426 450 \nOne tap mobile\n+16699006833\,\,415426450# US (San Jose)\n+13462487799\,\,415426450# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\n+1 253 215 8782 US\n+1 301 715 8592 US\nMeeting ID: 415 426 450\nFind your local number: https://lbnl.zoom.us/u/acBxMxIpwT \nJoin by SIP\n415426450@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n221.122.88.195 (China)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n209.9.211.110 (Hong Kong)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 415 426 450 \n──────────
