Some studies on the recent flavor anomalies

Abstract

This thesis discuss the rare decays b which shows significant devi-ations from Standard Model predictions. Here, we discussed the Standard Model, Flavour Structure, Neutral currents, Charged currents, and possi bilities of FCNC at tree level and loop levels. We try to reproduce the Standard Model prediction of Rk values. We try to understand statistical methods to understand data and graphs of experiments of Rk. The LHCb detector at CERN collected in beauty quarks decays, RK ⇥RK⇥ measurements show the violation of lepton universality and 3.1⇥ deviation from standard model prediction. Further experimental runs give us more confidence in the search for the Beyond Standard Model.
