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- and two-loop effective potential corrections to the Higgs masses, the model is able to describe the experimentally observed $μ (h_{95})_{γ γ}$ and $μ (h_{95})_{b \bar{b}}$ signal strengths. In addition, we also present the impacts of the LRSSM-specific parameters $\tan β_{R}$ , $v_{R}$ , and $v_{S}$ on the theoretical predictions of the signal strengths for the 95 and 125 GeV neutral Higgs bosons.
