We propose a scenario to generate flavor violating ${Z}^{\ensuremath{'}}$ interactions at one-loop level by introducing $U(1{)}_{\ensuremath{\mu}\ensuremath{-}\ensuremath{\tau}}$ gauge symmetry, extra vectorlike quark doublets ${Q}_{a}^{\ensuremath{'}}$, and a singlet scalar $\ensuremath{\chi}$. Both ${Q}_{a}^{\ensuremath{'}}$ and $\ensuremath{\chi}$ are charged under $U(1{)}_{\ensuremath{\mu}\ensuremath{-}\ensuremath{\tau}}$ and carry odd dark ${Z}_{2}$ parity. Assuming that $\ensuremath{\chi}$ is the dark matter (DM) …
