SUMMARY:VIRTUAL INPA SEMINAR – Adrien Hourlier (MIT)
DESCRIPTION:Speaker: Adrien Hourlier (MIT) \nTitle: MiniBooNE Oscillation Results with Complete Dataset \nAbstract: \nThe MiniBooNE experiment\, located on the Booster Neutrino Beamline at Fermilab\, reports a total excess of 638.0+/-132.8 electron-like events (4.8σ) from a data sample corresponding to 18.75×10^20 protons-on-target in neutrino mode\, which is a 46% increase in the data sample with respect to previously published results\, and 11.27 × 10^20 protons-on-target in antineutrino mode. The additional statistics allow several studies to address questions on the source of the excess. I will discuss how we can use distributions such as beam timing and the radial distribution to disfavor some of the possible explanation for the source of the excess such as an excess of entering or exiting photons. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/94852394075?pwd=cEFONlJ6UEVnRVBSU2liSnlIL0VhQT09 \nMeeting ID: 948 5239 4075\nPasscode: 295449

SUMMARY:VIRTUAL INPA SEMINAR | Scott Kravitz (LBNL)
DESCRIPTION:Speaker: Scott Kravitz (LBNL) \n \n\n\nTitle: CrystaLiZe – Solid Xenon Detector R&D\n \nAbstract: \nRadon and its daughter decays limit the sensitivity of direct WIMP dark matter searches\, despite extensive screening programs\, careful material selection and specialized Rn-reduction systems. For xenon time projection chambers\, a means to surpass this constraint may lie in crystallizing the xenon. In a solid matrix\, each of the decay steps surrounding the problematic radon daughter beta decay isotopes could be vetoed at the fixed position of the decay sequence. The constraint of time structure in the sequence could allow veto efficiency to approach 100%\, with minimal effect on acceptance. In this case\, the limiting background for WIMP searches would be neutrinos from the sun and from cosmic ray muons. It is additionally hypothesized that crystalline xenon may offer improved particle discrimination compared with liquid. In this talk\, I will argue that an instrumental radon tag in a crystalline xenon TPC may be the quickest path to reaching the neutrino floor and present preliminary results from a test stand which suggest that solid Xe is a viable particle detection medium.\n\nThe video for this talk will be posted:\nhttps://physicstalks.lbl.gov/Public/2020/rpm/ScottKravitz0.html\n\n\nJoin Zoom Meeting \nhttps://us04web.zoom.us/j/76619726361?pwd=Q2NRUHkzK0NZYUtLUWJIK2dEUzVhQT09\n\n\nMeeting ID: 766 1972 6361\n\n\nPasscode: 023744

SUMMARY:VIRTUAL INPA SEMINAR | Kev Abazajian (UC Irvine) 
DESCRIPTION:Speaker: Kev Abazajian (UC Irvine) \n\n \n\n\nTitle: Arising and demising candidate dark matter signals on the sky\, and the potential of future searches\n \nAbstract: \nNew  technologies searching are observing the high-energy Universe with unprecedented detail. One of the primary goals of gamma-ray and X-ray astronomy has been the search for potential signals of dark matter that could be at the keV to GeV energy scales. The past 10 years have had two candidate signals in both energy regimes\, which are both high energy but separated by a factor of 1 million: the ~3 GeV excess from the Milky Way Galactic Center\, and the 3-55 keV line detected in several X-ray observations. I will discuss the saga of these signals and future prospects from the keV to TeV scales.\n\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/93708191260  \nMeeting ID: 937 0819 1260\nPasscode: 521406

SUMMARY:VIRTUAL INPA SEMINAR | Sukanya Chakrabarti (RIT)
DESCRIPTION:Speaker: Sukanya Chakrabarti (Rochester Institute Technology) \nTitle: Measuring Accelerations— Near & Far \nAbstract: \nRecent technological advances and observational programs now make it possible for us to directly measure the Galactic acceleration experienced by stars within the Milky Way. I will discuss the traditional method of estimating Galactic accelerations and thereby the Oort limit (from which one determines the local dark matter density given the baryon budget)\, which uses kinematical estimates that can be inaccurate especially in parts of the Galaxy that are significantly perturbed. I will then discuss our method in using extreme precision radial velocity observations to measure the Galactic acceleration\, and ongoing observational programs. I will also use compiled pulsar timing data to directly measure the Galactic acceleration\, which gives us the Oort limit from the Poisson equation without making assumptions of equilibrium or spherical symmetry (as in kinematic estimates). Given the Oort limit\, we then determine the local dark matter density\, which has implications for direct detection experiments. I will discuss the potential for measuring dark matter sub-structure in the Milky Way with pulsar timing\, and for constraining theories of gravity by combining constraints from pulsar timing and extreme precision radial velocity measurements. Finally\, I will end by discussing prospects for measuring the cosmic acceleration. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/93826947056?pwd=Q3hGOVpBSVhQcDZqS2plaitYQVB6dz09 \nMeeting ID: 938 2694 7056 \nPasscode: 123733

SUMMARY:VIRTUAL INPA SEMINAR | Livia Ludhova (RWTH)
DESCRIPTION:Speaker: Livia Ludhova (RWTH Aachen/Forschungszentrum Jülich)\n \n\n\nTitle: JUNO: the first multi-kton liquid scintillator based neutrino detector\n \nAbstract:  \nThe Jiangmen Underground Neutrino Observatory (JUNO) is a neutrino experiment under construction in a 700 m deep underground laboratory near Jiangmen in South China. The detector main component will be 20 kton of liquid scintillator held in a spherical acrylic vessel. The experiment is designed for the determination of the neutrino mass ordering\, one of the open key questions in neutrino physics. This measurement will be based on the observation of vacuum oscillation of antineutrinos from two nuclear power plants at 53 km baseline. A key ingredient for the success is an excellent and extremely challenging energy resolution of 3% at 1 MeV. The light produced by the scintillator will be seen by about 20\,000 large PMTs (20”) and about 25\,000 small PMTs (3”). The OSIRIS detector will monitor the radio-purity of the liquid scintillator during the months-long filling of the main detector\, while the unoscillated spectrum from one reactor core is planned to be closely monitored by the Taishan Antineutrino Observatory (TAO). JUNO will also measure several neutrino oscillation parameters with unprecedented sub-percent precision. Astrophysical measurements of solar\, geo\, supernova\, DSNB\, atmospheric neutrinos\, as well as searches for proton decay or dark matter are also a part of the vast physics programme. The seminar will review the physics goals\, design\, as well as the status of the JUNO project.\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95227577412?pwd=bHdqOGVKSTlzaEdUbXF3emt1UGZ1dz09 \nMeeting ID: 952 2757 7412\nPasscode: 927741
