Is the Higgs Boson Composed of Neutrinos?

TL;DR

This paper proposes a novel model where the Higgs boson is composed of neutrinos, achieved through specific high-energy Yukawa couplings and interactions with a dark matter sector, offering a new perspective on electroweak symmetry breaking.

Contribution

It introduces a next-to-minimal dynamical electroweak symmetry breaking scheme where neutrinos form the Higgs boson via high-energy Yukawa couplings and dark matter interactions.

Findings

Higgs compositeness conditions can be met with neutrino-based Yukawa couplings.

A Higgs portal interaction with dark matter enhances the quartic coupling.

The model operates at energy scales around 10^{13}-10^{14} GeV.

Abstract

We show that conventional Higgs compositeness conditions can be achieved by the running of large Higgs-Yukawa couplings involving right-handed neutrinos that become active at $\sim 10^{13}- 10^{14}$ GeV. Together with a somewhat enhanced quartic coupling, arising by a Higgs portal interaction to a dark matter sector, we can obtain a Higgs boson composed of neutrinos. This is a "next-to-minimal" dynamical electroweak symmetry breaking scheme.
