Multi--lepton Signatures from $U(1{)}_{L_{\mu }-L_{\tau }}$ at the LHC

Jochem Kip, Zhongyi Zhang

The $U(1{)}_{L_{\mu }-L_{\tau }}$ extended Standard Model (SM) is anomaly free, and contains a massive $Z^{\prime }$ boson. The associated Higgs, which generates the $Z^{\prime }$'s mass via spontaneous sy…
