TL;DR

This paper explores how neutrino masses can be generated through lepton number violation involving charged scalar particles, analyzing the phenomenological implications of such models.

Contribution

It investigates the phenomenological consequences of neutrino mass generation via lepton number violation with charged scalars, extending the Zee mechanism.

Findings

Charged scalars can induce neutrino masses through lepton number violation.

Phenomenological implications include potential signals in collider experiments.

The model provides an alternative to traditional neutrino mass generation mechanisms.

Abstract

If there exist only three light neutrinos below the weak scale, the neutrino masses can arise by breaking the lepton number L. One example is the Zee mechanism for the neutrino masses. We study phenomenological implications of neutrino masses arising from the L violation through introduction of SU(2) X U(1) singlet scalars with Q_{em}=1 and 2.
