Dynamical seesaw mechanism for Dirac neutrinos

TL;DR

This paper introduces a new dynamical seesaw mechanism that explains the Dirac nature and small mass of neutrinos, potentially observable at current collider energies.

Contribution

It proposes a novel variant of the seesaw mechanism that makes the neutrino mass generation scale accessible to LHC experiments.

Findings

Neutrinos are modeled as Dirac particles with small masses.

The mechanism links neutrino mass to testable energy scales.

Potential experimental signatures at the LHC.

Abstract

So far we have not been able to establish that, as theoretically expected, neutrinos are their own anti-particles. Here we propose a dynamical way to account for the Dirac nature of neutrinos and the smallness of their mass in terms of a new variant of the seesaw paradigm in which the energy scale of neutrino mass generation could be accessible to the current LHC experiments.
