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, $e^+ e^- \rightarrow \gamma Z^\prime \rightarrow \gamma… 13 Citations ## Figures from this paper Dark matter and B -meson anomalies in a flavor dependent gauge symmetry • Physics Physical Review D • 2019 A possibility of explaining the anomalies in the semileptonic$B$-meson decay$B \to K^{*} \mu \bar\mu$has been explored in the framework of the gauged$U(1)_{\mu-\tau}$symmetry.

The energy spectrum of high-energy neutrinos reported by the IceCube Collaboration shows a dip between 400 TeV and 1 PeV. One intriguing explanation is that high-energy neutrinos scatter with the
