Description
In this talk, we discuss a scenario to generate flavor violating $Z'$ interactions at one loop level, by introducing $U(1)_{\mu-\tau}$(-like) gauge symmetry, extra vectorlike quark doublets $Q'_a$ and singlet scalar $\chi$. Both $Q'_a$ and $\chi$ are charged under $U(1)_{\mu-\tau}$ and carry odd dark $Z_2$ parity. Assuming that $\chi$ is the dark matter (DM) of the universe and imposing various constraints from dark matter search, flavor physics and collider search for $Q'_a$, one can show that radiative corrections to $b \rightarrow s Z^{'*} \rightarrow s \ell^+ \ell^-$ involving $Q'_a$ and $\chi$ can induce $\Delta C_9 \sim -1$ which can resolve the LHCb anomalies related with $B \to K^{(*)} \ell^+ \ell^-$. Therefore both DM and $B$ physics anomalies could be accommodated in the model.
