SUMMARY:VIRTUAL SEMINAR Special INPA / Research Progress Meeting\, Friday\, July 17\, 2020 – Michelle Galloway (University of Zurich)
DESCRIPTION:Speaker: Michelle Galloway (University of Zurich) \nTitle: Observation of excess electronic recoil events in XENON1T \nAbstract: A search for new physics with XENON1T revealed an excess of electronic recoil events in the (1 – 7) keV region\, favoring signal over background with significances of 3.5 sigma for solar axions/ALPs\, 3.2 sigma for an enhanced neutrino magnetic moment\, and 3.0 sigma global (4.0 local) for bosonic dark matter with a peak at 2.3 +- 0.2 keV (68% C.L.). Additionally\, a previously undetected tritium component\, favoured at 3.2 sigma over known backgrounds\, can neither be confirmed nor excluded. I will provide an overview of the XENON1T detection and analysis methods for this search\, a characterization of the excess events\, and present results for both possible backgrounds and potential new physics. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98002426771?pwd=R3dtTFhmb0ZyR0ZHV1E5amZCcnFBZz09 \nMeeting ID: 980 0242 6771\nPassword: 531232

SUMMARY:VIRTUAL INPA SEMINAR – Hao Chen (Texas A&M University)
DESCRIPTION:Speaker: Hao Chen (Texas A&M University) \nTitle: Two New Cryogenic Detector R&D \nAbstract: It is well-accepted that the majority of the matter in the universe is dark and non-baryonic. The nature of dark matter\, however\, remains mysterious. Various proposed candidates span a wide range in the mass and cross section parameter space. Many experimental efforts have been made aiming to detect dark matter particles directly\, part of the region in the parameter space has been excluded from their data. Probing the lower mass region requires a low threshold detection technique. I will talk about two new cryogenic detectors that are currently under development. The magnetic bubble chamber utilizes a single-molecule magnet as the target\, amplifying the signal from a scattering event by magnetic avalanches. The phonon-mediated high-voltage detector combines features of CDMS iZip and HV detector\, provides a possible way to achieve a low threshold without losing the electron recoil/nuclear recoil discrimination. \nCORRECTION Updated meeting ID and password information \nJoin Zoom Meeting https://lbnl.zoom.us/j/96636700595?pwd=bWcvZU9MQmdYdzE1YzNrZXdROElJQT09 \nMeeting ID: 966 3670 0595  \nPassword: 419873

SUMMARY:SPECIAL VIRTUAL INPA SEMINAR – Geertje Heuermann (Karlsruhe Institute of Technology)
DESCRIPTION:Speaker: Geertje Heuermann (Karlsruhe Institute of Technology) \nTitle: Active Shielding for Future Large-Scale Dark Matter Experiments\n \nAbstract: In this talk I will present the conceptual design of a water Cherenkov detector and a loaded liquid scintillator which effectively allow to reduce cosmogenic and radiogenic background sources in tonne scale dark matter detectors. \nJoin Zoom Meeting https://lbnl.zoom.us/j/94627104366?pwd=K09lTTBHdk5UVEw1cm1EOEVxVU05QT09 \nMeeting ID: 946 2710 4366  \nPasscode: 808254

SUMMARY:VIRTUAL INPA SEMINAR – Gioacchino Ranucci (INFN) Italy
DESCRIPTION:Speaker: Gioacchino Ranucci (INFN) Italy \nTitle: First detection of solar neutrinos from the CNO cycle with Borexino \nAbstract: The liquid scintillator detector Borexino reported recently the direct observation of neutrinos produced in the carbon-nitrogen-oxygen (CNO) fusion cycle in the Sun. This is the first experimental evidence of the existence of such reaction sequence in a star. The CNO solar neutrino interaction rate is 7.2 +3.0 −1.7 counts per day per 100 tons of target at 68% C.L.\, corresponding to a flux of neutrinos on Earth of 7.0 +3.0 −2.0 ×108 cm−2 s −1. The absence of CNO signal is disfavored at 5.0σ. In this seminar\, I will describe the technological effort to stabilize the detector and understand the background\, which is at root of this achievement\, together with the main features of the analysis procedure exploited to extract the CNO signal. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/96603938296?pwd=UWZERUphMlVqS0hReVozQ2dFdjU1dz09 \nMeeting ID: 966 0393 8296\nPasscode: 484158

SUMMARY:VIRTUAL INPA SEMINAR –  Jared Vann (Univ. of Liverpool)
DESCRIPTION:Speaker: Jared Vann (University of Liverpool) \nTitle: ARIADNE: Fast Optical Readout of Dual-Phase LArTPCs with Timepix3 Cameras \nAbstract: The ARIADNE experiment is a 1-ton dual-phase LArTPC with a novel optical readout method developed for applications in future Neutrino detectors. Optical readout is a potential alternative to existing charge based readouts in dual phase LArTPCs. The method was first shown to work by the ARIADNE experiment using CCD cameras. Now with extremely fast Timepix3 Cameras we can demonstrate full 3D readout with excellent resolution and calorimetry information. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/92513817972?pwd=MzhqWHptbzgxQVorRTlUTk45S1ZZQT09 \nMeeting ID: 925 1381 7972\nPasscode: 343374
