A Radiatively induced Elementary Goldstone Higgs in SU(4)/Sp(4)

TL;DR

This paper explores a model where the Higgs boson emerges as a pseudo-Goldstone boson from an SU(4)/Sp(4) symmetry breaking pattern, with radiative corrections determining its properties and spectrum.

Contribution

It presents a renormalizable, ultraviolet-complete model where the Higgs is a pseudo-Goldstone boson, with a detailed analysis of its vacuum structure and mass spectrum.

Findings

Higgs mass generated radiatively in the model

Scalar spectrum lies in the multi-TeV range

Vacuum alignment determined dynamically by perturbative corrections

Abstract

Using a $SU(4)\rightarrow Sp(4)$ pattern of chiral symmetry breaking, we investigate the pseudo-Goldstone nature of the Higgs boson in an elementary realisation that at the same time provides an ultraviolet completion. The renormalizability of the model together with the perturbative corrections determine dynamically the direction of vacuum of the theory and the corresponding Higgs chiral symmetry breaking scale $ f \sim 14~$TeV. The Higgs boson is radiatively generated and the scalar mass spectrum, together with a second massive Higgs boson, lie in the multi-TeV range.
