The 95 GeV and 125 GeV Higgs Excesses in the Left-Right Supersymmetric Standard Model

TL;DR

This paper explores how the Left-Right Supersymmetric Model can explain the observed excesses at 95 GeV and 125 GeV in Higgs-related experiments, incorporating loop corrections and specific model parameters.

Contribution

It demonstrates that the LRSSM can account for the experimental Higgs excesses by including loop corrections and analyzing the effects of model-specific parameters.

Findings

LRSSM can reproduce the observed 95 GeV Higgs excesses.

Model parameters significantly influence Higgs signal strength predictions.

Loop corrections are crucial for accurate Higgs mass calculations.

Abstract

This study investigates the excesses observed around 95 GeV in diphoton and $b\bar{b}$ experiments within the framework of the Left-Right Supersymmetric Model (LRSSM). Considering the one-loop and two-loop effective potential corrections to the Higgs masses, the model is able to describe the experimentally observed $\mu(h_{95})_{\gamma\gamma}$ and $\mu(h_{95})_{b\bar{b}}$ signal strengths. In addition, we also present the impacts of the LRSSM-specific parameters $\tan\beta_{R}$, $v_{R}$ and $v_{S}$ on the theoretical predictions of the signal strengths for the 95 GeV and 125 GeV neutral Higgs both.
