Flavour anomalies in supersymmetric scenarioswith non-minimal flavour violation / Boussejra, M.A. ; Mahmoudi, F. ; Uhlrich, G.
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 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 flavor anomalies, together with the anomalous muon magnetic dipole moment $(g-2)_\mu$.

Discrete $R$-symmetry, Various Energy Scales and Gravitational Waves / Choi, Gongjun ; Lin, Weikang (Shanghai Jiao Tong U.) ; Yanagida, Tsutomu T.
We present a supersymmetric model where energy scales of a discrete $R$-symmetry breaking ($Z_{6R}$) and cosmic inflation are commonly attributed to the confinement scale of a hidden $Sp(2)$ strong dynamics. [...]
