Vacuum alignment and radiatively induced Fermi scale

TL;DR

This paper explores how quantum corrections can induce vacuum misalignment in models with elementary scalars, proposing a framework where the hierarchy between unification and Fermi scales arises radiatively, linking these fundamental scales.

Contribution

It introduces a renormalisable model with elementary scalars demonstrating radiative hierarchy generation and vacuum misalignment, extending previous composite Higgs discussions.

Findings

Hierarchy between unification and Fermi scales emerges radiatively

Vacuum misalignment can be induced by quantum corrections in elementary scalar models

Framework links unification scale physics with electroweak symmetry breaking

Abstract

We extend the discussion about vacuum misalignment by quantum corrections in models with composite pseudo-Goldstone Higgs boson to renormalisable models with elementary scalars. As a concrete example, we propose a framework, where the hierarchy between the unification and the Fermi scale emerges radiatively. This scenario provides an interesting link between the unification and Fermi scale physics.
