The Private Higgs

TL;DR

This paper proposes a model with individual Higgs fields for each fermion to explain mass hierarchies, with implications for collider physics, dark matter, and flavor-changing processes.

Contribution

It introduces a novel 'private Higgs' framework that assigns separate Higgs fields to each fermion, addressing mass hierarchy issues and predicting new phenomena.

Findings

Potential new Higgs particles at TeV scale

Implications for dark matter candidates

Predictions of flavor-changing neutral currents

Abstract

We introduce Higgs democracy in the Yukawa sector by constructing a model with a private Higgs and a dark scalar for each fermion thus addressing the large hierarchy among fermion masses. The model has interesting implications for the LHC, while the Standard Model phenomenology is recovered at low energies. We discuss some phenomenological implications such as FCNC, new Higgses at the TeV scale and dark matter candidates.
