Study of Gauged Lepton Symmetry Signatures at Colliders

Understand

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 $Z_\ell$.
