| Abstract: | The Standard Model of particle physics predicts lepton universality. In 2021, LHCb Collaboration presented evidence for the violation of lepton universality in beauty quark decays, but more precision is needed to proof it with higher significance. After upgrading the accelerator and the detector, the new LHCb Run 3 data coming in 2022 will enable further analysis of such decays. In this work, the efficiency of the new detector has been studied for decay modes B± → J/Ψ(→ e+e−)K±, B± → J/Ψ(→ μ+μ−)K±, B± → Ψ(2S)(→ e+e−)K±, B± → Ψ(2S)(→ μ+μ−)K±. Also the expected number of detected events per luminosity unit has been computed for these four decay modes, and compared with its value before the upgrade |
