Charming Higgs

TL;DR

This paper proposes a supersymmetric model where the Higgs predominantly decays into four charm quarks via a light pseudoscalar, allowing a Higgs mass below 100 GeV without experimental conflict, addressing the little hierarchy problem.

Contribution

It introduces a simple supersymmetric framework with a novel decay mode for the Higgs, leveraging pseudo-Goldstone bosons to resolve the little hierarchy problem.

Findings

Higgs decays mainly to 4 charm quarks via eta

Higgs mass can be below 100 GeV without conflict

Model addresses the little hierarchy problem

Abstract

We present a simple supersymmetric model where the dominant decay mode of the lightest Higgs boson is h->2eta->4c where eta is a light pseudoscalar and c is the charm quark. For such decays the Higgs mass can be smaller than 100 GeV without conflict with experiment. Together with the fact that both the Higgs and the pseudoscalar eta are pseudo-Goldstone bosons, this resolves the little hierarchy problem.
