Description
Over the past decade, the LHCb and CMS experiments have reported persistent tensions in several branching fractions and angular observables of exclusive $b \to s \mu^+\mu^-$ decays. 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 present a new strategy that exploits forthcoming measurements to distinguish possible New Physics contributions from nonperturbative QCD effects.
