A light shed on decays of heavy flavored mesons

• Sonali Patnaik (College of Basic Science and Humanities, OUAT, India)

At the back of succeeding measurements of anomalies in semileptonic decays at several collider experiments hinting at the possible violation of lepton flavor universality, we undertake a concise review of theoretical foundations of the tree- and loop-level b-hadron decays along with experimental environments. We revisit the world averages for $R_{D(D^*)}$, $R_{K(K^*)}$, $R_{J/\psi}$ and $R_{\eta_c}$, and provide results within the framework of the relativistic independent quark model in addition to the results from model-independent studies. A confirmation of these measurements would soon turn out to be the first observation of physics beyond the Standard Model giving a wider outlook on the better understanding of new physics.
