Study of gauged lepton symmetry signatures at colliders

We construct a new gauged U(1)(l) lepton-number model that is anomaly-free for each standard model generation. The active neutrino masses arc radiatively generated with a minimal scalar sector. The phenomenology and collider signals are studied. The interference effects among the new gauge boson, Z(l), 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(l). Moreover, the electroweak precision sets a stringent bound on the mass splitting of the new lepton doublets.
