Flavour anomalies in supersymmetric scenarios with non-minimal flavour violation

Abstract

Motivated by tensions between experimental measurements and SM predictions in $b\to s{\ell }^{+}{\ell }^{-}$ transitions, we present the first study of non-minimal flavour-violating Minimal Supersymmetric Standard Model (MSSM) scenarios contributing to the relevant Wilson coefficients to address the observed anomalies using SuperIso and MARTY. We calculate the full one-loop analytical contributions of the general MSSM to Wilson coefficients relevant for flavour anomalies, together with the anomalous muon magnetic dipole moment $(g-2{)}_{\mu }$. We show that, after imposing theoretical constraints on the flavour-violating parameters we can find scenarios in agreement with the experimental measurements that can address at the same time the tensions in flavour observables and in $(g-2{)}_{\mu }$.
