SUMMARY:Speaker: Stefania Gori (UCSC)-Title: New meson probes of axion-like-particles
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate: MAY 2\, 2023 \nLocation: Sessler Conference Room – 50A-5-5132 \nSpeaker: Stefania Gori (UCSC) \nTitle: New meson probes of axion-like-particles \nAbstract: \n\nMeson factories are at the cutting edge of the intensity frontier\, with an unprecedented number of pions\, Kaons\, and B mesons that will be produced in the coming years. In addition to precise measurements of Standard Model processes\, these experiments have a unique opportunity to search for dark sector particles in the sub-GeV mass range. In this talk\, we will first give an overview of new opportunities to search for axion-like particles (ALPs) in light meson decays. Such ALPs can be motivated by a solution to the hierarchy problem\, the strong CP problem\, the flavor puzzle\, and combinations of these with DM physics.  Second\, we revisit the theory and constraints on ALPs interacting with leptons\, pointing out the relevance of charged current meson and W decays to ALPs. This is particularly prominent in models where the ALP couples in an isospin-violating way. Finally\, we highlight the role of the future PIONEER experiment in probing these new charged current pion decays to ALPs.\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182\nPasscode: 169037

SUMMARY:Speaker: Frank Qu (Cambridge University) - Title: Cosmology from high-precision CMB lensing measurements with the Atacama Cosmology Telescope
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate: MAY 18\, 2023 \nLocation: Sessler Conference Room – 50A-5-5132 \nSPEAKER: Frank Qu (Cambridge University) \nTITLE: Cosmology from high-precision CMB lensing measurements with the Atacama Cosmology Telescope \nABSTRACT: \nThe cosmic microwave background provides a unique backlight for illuminating the growth of structures in our universe. Measuring the arcminute-scale lensing deflections experienced by the CMB photons as they travel to our telescopes enables the mapping of the matter distribution to very high redshifts. This lensing signal provides a clean window for constraining fundamental physics\, such as the sum of neutrino masses\, and enables powerful tests of the standard cosmological model via comparison of high-precision measurements of structure growth at late times with early-time predictions. \n  \nIn this talk\, I will present new CMB lensing measurements derived from data release 6 of the Atacama Cosmology Telescope. Our work provides a state-of-the-art lensing power spectrum measurement and an associated signal-dominated lensing mass map that enable a host of cosmological and astrophysical science goals. I will first discuss the novel methods used to tackle key systematics affecting precision CMB lensing. I will then explore the implications of our measurements for tests of cosmic structure growth and the S8 tension. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\nPasscode: 142239

SUMMARY:[SPECIAL RPM] Speaker: Marcel Vos (IFIC (UV/CSIC) Valencia)
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate: MAY 22\, 2023 \nLocation: Sessler Conference Room – 50A-5-5132 \nSpeaker: Marcel Vos (IFIC (UV/CSIC) Valencia) \nTitle: “The third-generation quarks and the Higgs boson – from the LHC to the next large-scale facility in HEP” \nAbstract: In this seminar I discuss a number of selected topics in studies of the bottom and top quarks. A few recent highlights of the top quark physics program of the ATLAS and CMS experiments at the LHC are presented. These results continue to improve the precision that can be achieved at a hadron collider and expand the energy frontier beyond several TeV. An extensive search program open ups increasingly rare top quark production processes\, providing access to couplings that had not been tested directly so far. To provide a broader perspective\, current results are compared to the prospects of the High Luminosity phase of the LHC and of a future electron-positron collider. The seminar finalizes with a discussion of a proposal to use the interactions of the bottom (and top) quarks with the Higgs boson to test the evolution of particle masses with energy predicted by the Standard Model. \n\nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/96855892866?pwd=dEltOWdIdHZSSHlBRGJiUXlQdm1Pdz09 \nMeeting ID: 968 5589 2866\nPasscode: 915719

SUMMARY:Speaker: Eric Torrence (University of Oregon)- Title: Precision Luminosity with the ATLAS Experiment
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate: MAY 25\, 2023 \nLocation: Sessler Conference Room – 50A-5-5132 \nSPEAKER: Eric Torrence (University of Oregon) \nTITLE: Precision Luminosity with the ATLAS Experiment\n \nABSTRACT: Abstract:  A precise measurement of the integrated luminosity is a key component of the ATLAS physics program at the CERN LHC. This measurement is based on an absolute calibration of the LUCID detector using dedicated van der Meer beam-separation scans\, and extrapolated to physics conditions with a set of complimentary measurements from the ATLAS inner detector and calorimeter systems. Evaluated for all physics data recorded during the LHC Run2 data taking (from 2015-18)\, the uncertainty on the integrated luminosity delivered to ATLAS has achieved a relative precision of 0.8%. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\nPasscode: 142239
