Title: Lepton-flavor-universality and Lepton-flavor-Violation in b->s transitions

Speaker: Dr. Seema Choudhury, Iowa State University

Abstract:

Lepton flavor universality violation (LFUV) in B decays could be a hint for new physics. This talk will summarize the latest results on LFUV observables RK and RK*, the branching fraction of B→ K (∗)μ+μ− to B→K(∗) e+e− . If there is new physics, it can be uniquely observed by studying angular observables like P5’, Q5 in B→ K∗l+l− decays. I will also show the differential branching fraction and CP-averaged isospin asymmetries, AI measurements. The LFUV accompanies lepton flavor violation (LFV), and here I will summarize the results of B→ K (∗)μ+e− decays. All results will focus on the Belle/Belle II and LHCb data.
