Neutrino masses and the extra Z^{\prime 0}

TL;DR

This paper proposes a framework where neutrino masses and an extra Z' boson are generated through an extended Higgs sector, potentially linking dark matter to neutrinos and Z' interactions with visible matter.

Contribution

It introduces a 2+2 Higgs scenario as a natural mechanism for generating neutrino and Z' masses, connecting dark matter to neutrino and Z' interactions.

Findings

Neutrino masses can be explained via an extended Higgs sector.

The extra Z' boson mass arises naturally in this framework.

Dark matter interactions are primarily through neutrinos and Z' bosons.

Abstract

We now know firmly that neutrinos have tiny masses, but in the minimal Standard Model there is no natural sources for such tiny masses. On the other hand, the extra heavy Z^{\prime 0} requires the extra Higgs field, the particle generating the mass. Here I propose that the previous 2+2 Higgs scenario could be a natural framework for mass generations for both the neutrinos and the extra Z^{\prime)}. These particles are classified as the "dark matter". Hopefully all the couplings to the "visible" matter are through the neutrinos and the extra Z^{\prime 0}, explaining naturally why the dark matter is so dark to see.
