Could two NMSSM Higgs bosons be present near 125 GeV?

TL;DR

This paper explores the possibility that two Higgs bosons in the NMSSM model could both be near 125 GeV, potentially explaining observed signals with enhanced decay rates and broadened mass peaks.

Contribution

It investigates GUT-scale NMSSM scenarios where two Higgs bosons are simultaneously in the 123-128 GeV range, highlighting potential experimental signatures.

Findings

Both Higgs bosons can have enhanced decay rates.

Mass peaks can be naturally broadened.

Scenario is consistent with current experimental data.

Abstract

We examine GUT-scale NMSSM scenarios in which {\it both} $h_1$ and $h_2$ lie in the 123 -- 128 GeV mass range. Very substantially enhanced $\gamma\gamma$ and other rates are possible. Broadened mass peaks are natural.
