Based on recent HQET sum rule and lattice calculations we present updated Standard Model predictions for the mass differences of neutral B mesons:
∆M SM = 18.4+0.7 ps⁻¹ and ∆M SM = 0.533+0.022 ps⁻¹ and study their impact on s −1.2 d −0.036 new physics models that address the present hints of anomalous data in b → sℓℓ transitions. We also examine future prospects of further reducing the theory uncertainties and discuss the implications of a 2025 scenario with ∆MSM 2025 = (18.4 ± 0.5) ps⁻¹. In particular, the latter yields upper bounds MZ′ ≲ 9TeV and MS3 ≲ 30TeV for the minimal Z′ and S₃ lepto-quark explanations of the b → sℓℓ anomalies, respectively.
