Lepton-flavour violating $B$ decays in generic $Z'$ models
LHCb has reported deviations from the SM expectations in $B\to K^* \mu^+\mu^-$ angular observables, in $B_s\to\phi\mu^+\mu^-$ and in ratio $R(K)=Br[B\to K \mu^+\mu^-]/Br[B\to K e^+e^-]$. For all three decays, a heavy neutral gauge boson mediating $b\to s\mu^+\mu^-$ transitions is a prime candidate f...
