125 GeV Higgs boson decays in the $\mu$ from $\nu$ supersymmetric standard model

TL;DR

This paper explores how the $mbda$ from $ u$ supersymmetric standard model explains the decay signals of the 125 GeV Higgs boson, aligning with recent ATLAS and CMS experimental data.

Contribution

It investigates Higgs decay channels within the $mbda$ from $ u$SSM, highlighting the effects of light stop and stau particles on signal strengths.

Findings

Light stop and stau significantly influence Higgs decay signals.

The model can account for the updated experimental Higgs data.

Predictions align with observed decay channels at 125 GeV.

Abstract

Recently the ATLAS and CMS Collaborations have reported significant events that are attributed to the neutral Higgs boson with mass around 125 GeV. In this work, we investigate the signals of the Higgs boson decay channels $h\rightarrow\gamma\gamma$, $h\rightarrow VV^*$ ($V=Z,W$), and $h\rightarrow f\bar{f}$ ($f=b,\tau$) in the $\mu$ from $\nu$ supersymmetric standard model ($\mu\nu$SSM). In the numerical results, we show the light stop and stau effects on the signal strengths for the 125 GeV Higgs boson decay channels in the $\mu\nu$SSM, which can account for the updated experimental data on Higgs.
