Motivated by experimental hints and theoretical frameworks indicating the existence of an extended Higgs sector, we explore the feasibility of detecting a 95 GeV light Higgs boson decaying into a diphoton within the minimal dilaton model at the 14 TeV LHC. Initially, we identify the correlations between the production cross section, decay branching ratios, and model parameters, e. g. , the scalar mixing angle S. Subsequently, we utilize Monte Carlo simulations to generate the signal of the light Higgs boson via the pp tt (s) process, along with the corresponding backgrounds. To effectively separate the signal from the dominant backgrounds tt, we employ a meticulous cut-based selection process. Ultimately, we find that with an integrated luminosity of L = 3000 {~ fb^-1}, the regions of |S|>0. 2 can be covered over the 3 level.
