Monte Carlo Studies of B Meson Decays to Charged Leptons Plus a K-short meson in the ATLAS Detector at the LHC

The ratio of the rate of decay of B mesons to K-short mesons plus two oppositely charged muons relative to the same rate with oppositely charged electrons is referred to as R(K_s⁰). A measurement of this ratio probes lepton universality and thus may provide a window onto new physics. Studies of Monte Carlo simulations of these types of events produced in the ATLAS detector at center of mass energy 13 TeV are presented.
