Origin of the VEVs hierarchy

TL;DR

This paper proposes a non-minimal technicolour model explaining the hierarchy of VEVs, the flavor spectrum, neutrino properties, and experimental constraints, potentially allowing a lighter technicolour scale and a Higgs-like boson.

Contribution

It introduces a novel technicolour framework that accounts for VEVs hierarchy, flavor spectrum, neutrino masses, and experimental bounds simultaneously.

Findings

Lower bound on vector technicolour mass derived from S-parameter constraints

Model allows a lighter technicolour scale with a Higgs-like boson

Explains flavor spectrum and neutrino properties within the framework

Abstract

We present an origin of the VEVs hierarchy in a non-minimal technicolour framework which is capable of explaining the flavour spectrum of the standard model along with neutrino masses and mixing, and simultaneously satisfying crucial experimental bounds. The technicolour scale in this framework can be lower such that a standard model-like Higgs boson emerges from within the model. We also derive lower bound on the mass of the vector technicolour state using the latest experimental bound on the $S$-parameter.
