Abstract:

The study of lepton flavor universality violation (LFUV) offers a promising pathway for exploring new physics beyond the Standard Model, with the potential to indirectly probe the new physics at energy scales up to 10 TeV. Currently, an average LFUV with 3.3σ significance has been observed in the semileptonic decays of B mesons. The Belle II experiment has conducted the measurements of R(D*), the ratio of branching fractions for B→D*τν versus B→D*lν, as well as R(Xc), to investigate LFUV. This report will present several recent LFUV-related measurements from the Belle and Belle II experiments, and discuss the future prospects.
