摘要

实验提示和理论框架表明存在一个扩展的希格斯扇区,受此激励,我们探索了在 14 TeV 大型强子对撞机上探测 95 GeV 轻希格斯玻色子在最小稀拉顿模型中衰变为双光子的可行性。首先,我们确定了产生截面、衰变分支比和模型参数(如标量混合角)之间的相关性。随后,我们利用蒙特卡洛模拟,通过该过程产生轻希格斯玻色子信号以及相应的背景。为了有效地将信号与主要背景分离开来,我们采用了一种细致的基于剪切的选择过程。最终,我们发现,在综合光度为 ,的区域可以覆盖整个水平。

95 GeV light Higgs in the top-pair-associated diphoton channel at the LHC in the minimal dilaton model*
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 . Subsequently, we utilize Monte Carlo simulations to generate the signal of the light Higgs boson via the process, along with the corresponding backgrounds. To effectively separate the signal from the dominant backgrounds , we employ a meticulous cut-based selection process. Ultimately, we find that with an integrated luminosity of , the regions of can be covered over the level.
