AI 中文摘要
本文对标准模型的味依赖 $U(1)_X$ 扩展中类标准模型希格斯玻色子 $H$ 进行了唯象学研究，其中 $X$ 电荷根据费米子味分配。特别分析了 $H$ 与标准模型粒子以及新带电标量玻色子的相互作用。此外，研究了表征单圈水平 $H\to \gamma\gamma$ 衰变的参数 $\kappa_{\gamma}$。结果表明该模型预测的 $\kappa_{\gamma}$ 值在 $1\sigma$ 水平与ATLAS和CMS的约束一致，同时满足来自味、对撞机和暗物质研究的多个限制。
英文摘要
This work presents a phenomenological study of the Standard Model-like Higgs boson $H$ in a flavor-dependent $U(1)_X$ extension of the Standard Model, where the $X$ charge is assigned according to fermion flavors. In particular, we analyze the interactions of $H$ with Standard Model particles as well as with new charged scalar bosons. In addition, the parameter $\ka_{\ga}$, which characterizes the $H\to \ga\ga$ decay at the one-loop level, is investigated. The results show that the model predicts $\ka_{\ga}$ values consistent with the ATLAS and CMS constraints at the $1σ$ level, while satisfying several bounds derived from flavor, collider and dark matter studies.
