Description
In this talk I will show how one can account for the observed anomalies in $b\to s\mu^+\mu^-$ via loop effects with new scalars and fermions. Allowing for couplings to left- and right-handed quarks and leptons, we calculate the contributions to $b\to s\mu^+\mu^-$, $B-\bar{B}$ mixing and the anomalous magnetic moment of the muon.
I will show how, in a specific model in which we supplement the SM with a $4^{\rm th}$ generation of vector-like fermions and a real scalar field, one can address at the same time the observed anomalies in $b\to s\mu^+\mu^-$ and the anomalous magnetic moment of the muon.
