Recent Anomalies in B Physics

Original · EN

B physics plays important roles in searching for the new physics (NP) beyond the standard model (SM). Recently, some deviations between experimental data and SM predictions were reported, namely R(D⁽*⁾), P₅′ and Rₖ⁽*⁾ anomalies. If these anomalies were further confirmed in future, they would be unambiguous hints of NP. Theoretically, in order to explain these anomalies, a large number of models have been proposed, such as models including leptoquark or Z′. However, these new particles have not been discovered directly in LHC. Moreover, the models should pass the examination of Bₛ→ μ+μ- and Bₛ⁰- Bₛ⁰ mixing. In future, the analysis of data taken during the ongoing Run 2 of the LHC and the forthcoming Belle-II will present new insight both into the observables of interest and into new strategies to control uncertainties. Theoretically, the existed models should be further tested; and more NP models are welcomed to explain these anomalies simultaneously without affecting other measurements consistent with SM.
