A Higgs Doublet + Higgs Singlet Scheme with Negative Kinetic Term for Neutrino Mass Generation

TL;DR

This paper proposes a novel neutrino mass generation scheme involving a Higgs singlet and doublet with nonzero VEVs, favoring a normal hierarchy, and explicitly calculates the resulting neutrino masses.

Contribution

It introduces a new scheme with a Higgs singlet and doublet with nonzero VEVs for neutrino mass generation, emphasizing the normal hierarchy.

Findings

Normal hierarchy of neutrino masses is favored.

Explicit calculations of neutrino masses are provided.

The scheme extends the Standard Model with new Higgs fields.

Abstract

In this paper, we propose a scheme for neutrino mass generation. A Higgs singlet is introduced in the Standard Model of particle physics (SM). All of this new singlet and the charged and neutral Higgs fields in the original Higgs doublet are assumed to have nonzero vacuum expectation values (VEVs). The normal hierarchy of neutrino masses is evidently preferred in our scheme. The neutrino masses are explicitly calculated.
