The One Higgs and its Connections

TL;DR

This paper proposes a model with a single Higgs doublet responsible for electroweak symmetry breaking, linking it to dark matter stability and radiative generation of neutrino, quark, and lepton masses through symmetries.

Contribution

It introduces a symmetry-based framework that prevents mixing of additional scalars with the Higgs, naturally explaining dark matter stability and radiative mass generation.

Findings

Single Higgs doublet responsible for electroweak symmetry breaking

Radiative neutrino, quark, and lepton masses explained

Dark matter stability linked to symmetry constraints

Abstract

I propose the notion that there is only one Higgs doublet which is responsible for electroweak symmetry breaking and all other possible scalars in any extension of the standard model are prevented from mixing with it because of a symmetry which stabilizes dark matter. This leads naturally to radiative (scotogenic) neutrino mass as well as radiative quark and lepton masses if flavor symmetry is also considered.
