$$b \rightarrow c$$ b → c semileptonic sum rule: extension to angular observables
Abstract Lepton flavor universality is a key prediction of the Standard Model of particle physics, and any violation of it immediately indicates the existence of new physics. Given the recent discrepancy of more than $$4\sigma $$ 4 σ in charged current semileptonic B meson decays and the absence of...
