Signatures of supersymmetry and a Lμ−Lτ gauge boson at Belle-II
@article{Banerjee2019SignaturesOS, title={Signatures of supersymmetry and a L$\mu$−L$\tau$ gauge boson at Belle-II}, author={Heerak Banerjee and Sourov Roy}, journal={Physical Review D}, year={2019} }
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…
