SUMMARY: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"
DESCRIPTION:Abstract: \nThe 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.\n  \n  \n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# 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 (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n────────── \n

SUMMARY:Zara Bagdasarian (UCB) "Solar Neutrinos with Borexino: First Evidence of CNO Fusion Cycle"
DESCRIPTION:Abstract:\nThe prime energy producer in the sun is the fusion of hydrogen to form\nhelium. However\, there is more than one way for this fusion to take\nplace: for stars the size of the sun or smaller\, the proton-proton (pp)\nchain reactions dominate (~99%)\, while in heavier stars\, the\ncarbon-nitrogen-oxygen (CNO) cycle is expected to play a more important\nrole. Not only these fusion reactions would not have been possible\nwithout the emission of neutrinos\, neutrinos are the only way to\ndirectly access the processes in the core of the sun. \nBorexino experiment\, located at the Laboratori Nazionali del Gran Sasso\,\nwas built with a primary goal of the Be7 solar neutrinos (part of pp\nchain) detection. In more than a decade of data taking\, Borexino has not\nonly demonstrated the unprecedentedly high sensitivity towards Be7 solar\nneutrinos (<3%) but performed a comprehensive study of low-energy\nneutrinos from the complete pp-chain. After a number of developments in\nboth hardware and software\, Borexino presents the first experimental\nevidence of the up-to-now elusive CNO fusion cycle in the Sun. The\nabsence of the CNO neutrinos signal is disfavoured by the Borexino\nexperiment at 5σ. \n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# 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 (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────

SUMMARY:JOINT INPA/RPM Seminar | Michelle Galloway (University of Zurich) "Observation of excess electronic recoil events in XENON1T"
DESCRIPTION:Abstract:  \nA 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. \nhttps://lbnl.zoom.us/j/98002426771?pwd=R3dtTFhmb0ZyR0ZHV1E5amZCcnFBZz09 \nMeeting ID: 980 0242 6771\nPassword: 531232

SUMMARY:Josh McFayden (LBNL) "Unravelling LEP-Era Lepton Flavour Universality Discrepancy with ATLAS"
DESCRIPTION:Abstract:  \n\nA remarkable feature of the Standard Model (SM) is that each lepton flavour (electron\, muon\, tau) is equally likely to interact with a W boson. This is known as Lepton Flavour Universality. \n\n\nIn a recent ATLAS measurement\, a novel technique using events with top-quark pairs has been exploited to test the ratio of the probabilities for tau leptons and muons to be produced in W boson decays\, R(τ/μ). \n\n\nIn the SM\, R(τ/μ) is expected to be unity\, but a longstanding tension with this prediction has existed since the LEP era\, where\, from a combination of experiments\, R(τ/μ) was measured to be 2.7σ higher than the SM expectation. \n\nIf the LEP result were confirmed to O(1%) precision it would correspond to an unambiguous discovery of beyond the SM physics. This latest ATLAS measurement obtains this level a precision – please join the RPM to discover whether or not it agrees with LEP!\n\n\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95906405235 \nMeeting ID: 959 0640 5235\nOne tap mobile\n+16699006833\,\,95906405235# US (San Jose)\n+13462487799\,\,95906405235# 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 (Tacoma)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 959 0640 5235\nFind your local number: https://lbnl.zoom.us/u/a9dnGtb5T \nJoin by SIP\n95906405235@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 959 0640 5235 \n──────────
