Study of Gauged Lepton Symmetry Signatures at Colliders

Abstract

We construct a new gauged $U(1{)}_{\ell }$ lepton number model which is anomaly-free for each SM generation. The active neutrino masses are radiatively generated with a minimal scalar sector. The phenomenology and collider signals are studied. The interference effects among the new gauge boson, $Z_{\ell }$, photon, and $Z$-boson can be probed at the future $e^{+}{e}^{-}$ colliders even if the center-of-mass energy is below the mass of $Z_{\ell }$. Moreover, the electroweak precision sets a stringent bound on the mass splitting of the new lepton doublets.
