Abstract:It was previously shown that unlike the ratios RKμe≡RK≡Γ(B→Kμ+μ−)/Γ(B→Ke+e−) and RK*μe≡RK*≡Γ(B→K*μ+μ−)/Γ(B→K*e+e−), the ratios RKτμ and RK*τμ can deviate from their Standard Model (SM) predictions even with universal new physics couplings. This observation highlights the critical need to identify and establish genuine lepton flavor universality violating (LFUV) observables in the τ−μ sector. This work embarks on establishing genuine LFUV ratio observables in B→Kℓℓ and B→K*ℓℓ decays through comprehensive analys… Show more
