Findings

Gauge couplings unify at TeV-scale in the 3-3-1 model.

Neutrino masses arise from quantum corrections mediated by new gauge bosons.

Model predicts observable signatures at the LHC.

Abstract

The physics responsible for gauge coupling unification may also induce small neutrino masses. We propose a novel gauge mediated radiative seesaw mechanism for calculable neutrino masses. These arise from quantum corrections mediated by new $SU(3)_c \times SU(2)_L \times U(1)_X$ (3-3-1) gauge bosons and the physics driving gauge coupling unification. Gauge couplings unify for a 3-3-1 scale in the TeV range, making the model directly testable at the LHC.
