R(K(⁎)) from dark matter exchange
Hints of lepton flavor violation have been observed by LHCb in the rate of the decay B→Kμ+μ− relative to that of B→Ke+e−. This can be explained by new scalars and fermions which couple to standard model particles and contribute to these processes at loop level. We explore a simple model of this kind...
