We propose that the $\gamma + E \hspace{-.5em}/\;\:$ signal at the Belle-II will be a smoking gun for supersymmetry (SUSY) in the presence of a gauged $U(1)_{L_{\mu}-L_{\tau}}$ symmetry. A striking consequence of breaking the enhanced symmetry in the limit of degenerate (s)leptons is the non-decoupling of the radiative contribution of heavy charged sleptons, appearing in SUSY, to the $\gamma - Z^\prime$ kinetic mixing. The signal process, $e^+ e^- \rightarrow \gamma Z^\prime \rightarrow \gamma…

Dark matter and B -meson anomalies in a flavor dependent gauge symmetry
A possibility of explaining the anomalies in the semileptonic $B$-meson decay $B \to K^{*} \mu \bar\mu$ has been explored in the framework of the gauged $U(1)_{\mu-\tau}$ symmetry. Apart from the
Minimal gauged U(1)Lα−Lβ models driven into a corner
