Radiatively induced Fermi scale and unification

TL;DR

This paper presents a model where the Fermi scale arises radiatively from a unification scale, linking low-energy physics with a more fundamental high-energy framework, specifically within a Pati-Salam-type unification with an elementary pseudo-Goldstone Higgs.

Contribution

It introduces a concrete Pati-Salam-inspired model where the unification scale is fixed and the Fermi scale is generated radiatively, connecting high-energy unification with electroweak symmetry breaking.

Findings

The unification scale is fixed to a phenomenologically viable value.

The Fermi scale is generated radiatively within the model.

The scenario links unification physics with electroweak symmetry breaking.

Abstract

We propose a framework, where the hierarchy between the unification and the Fermi scale emerges radiatively. This work tackles the long-standing question about the connection between the low Fermi scale and a more fundamental scale of Nature. As a concrete example, we study a Pati-Salam-type unification of Elementary-Goldstone-Higgs scenario, where the Standard Model scalar sector is replaced by an SU(4)-symmetric one, and the observed Higgs particle is an elementary pseudo-Goldstone boson. We construct a concrete model where the unification scale is fixed to a phenomenologically viable value, while the Fermi scale is generated radiatively. This scenario provides an interesting link between the unification and Fermi scale physics, and opens up prospects for exploring a wide variety of open problems in particle physics, ranging from neutrinos to cosmic inflation.
