Abstract
Lepton universality is a property which is embedded in the Standard Model of Particle Physics. A violation of this universality would indicate the presence of physics beyond the Standard Model. In this work, the search for lepton universality violation is aided by investigating the possibility of using bremsstrahlung-related information, to increase the efficiency of particle identification of electrons in the LHCb detector. An ensemble of variables is created that, combined with machine learning tools, increases false positive rejection rates by 58.4% for upstream electrons.
