Characterization of 3D Sensors, Electron Isolation at the HL-LHC, and Testing Lepton Universality in ATLAS

Tuesday September 6, 2022
2:00 pm

 Presenter:  Andrew Gentry, UNM
 Series:  Nuclear, Particle, Astroparticle and Cosmology (NUPAC) Seminars
 Abstract:  The ATLAS detector has already recorded data from an integrated luminosity of 139 fb-1, and this is less than one tenth of the total dataset expected to be collected during the lifetime of the LHC. This data offers opportunities to make high-precision measurements of many physical processes that have the possibility of violating the Standard Model. The LHC will soon be undergoing an upgrade to achieve significantly higher luminosity. At the same time, ATLAS will be undergoing an upgrade of several of its detector subsystems. While higher luminosity will add to the statistical precision of future measurements, it will also lead to increased levels of radiation damage in the detector, and new challenges in accurately differentiating physical processes in our analyses. This talk will be an overview of studies involving radiation-hard 3D sensors, electron isolation in the upgraded ATLAS detector, and a test of lepton universality using decays of B mesons.
