Description
Over the past decade, the LHCb and CMS experiments have reported persistent tensions in several branching fractions and angular observables of exclusive rare semileptonic $b$-hadron decays ($b \to s \mu^+\mu^-$). Taken together, these discrepancies exceed the five-standard-deviation level. However, their interpretation remains the subject of active debate, particularly regarding the size and treatment of nonperturbative QCD effects. In this talk, I review the current experimental and theoretical status of these anomalies and discuss the prospects for resolving their origin with upcoming measurements and improved theoretical calculations.
