Abstract
Based on recent HQET sum rule and lattice calculations we present updated Standard Model predictions for the mass differences of neutral B mesons: ΔMSMs=(18.4+0.7−1.2)ps−1 and ΔMSMd=(0.533+0.022−0.036)ps−1 study their impact onnew 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 ΔMSM2025s=(18.4±0.5) ps−1. In particular, the latter yields upper bounds MZ′ ≲ 9TeV and MS3≲30TeVfor the minimal Z′ and S3 lepto-quark explanations of the b → sℓℓ anomalies, respectively.
