论文摘要
一个具有可口的Yukawa结构的两个Higgs Doublet模型，其中两个双重组分别为第三代和前两代，与Twin Higgs机制结合使用，以稳定Higgs质量，以防止辐射校正。我们认为镜子双胞胎和兄弟双胞胎设置。我们将希格斯信号强度测量和衰减$ b_s \至μμ$确定为模型参数空间的最重要的间接约束。我们探索了模型的对撞机现象学，并发现可见扇区中的沉重希格斯可以在参数空间区域内将大量流离失所的衰减成$ b $ jets，其中Smlike Higgs和Twin Higgs没有提供任何引人注目的签名。
A two Higgs doublet model with flavorful Yukawa structure, in which the two doublets give mass to the third and the first two generations respectively, is combined with the twin Higgs mechanism to stabilize the Higgs mass against radiative corrections. We consider both a mirror twin and fraternal twin setup. We identify Higgs signal strength measurements and the decay $B_s \to μμ$ as the most important indirect constraints on the parameter space of the model. We explore the collider phenomenology of the model and find that the heavy Higgs in the visible sector can give a sizable number of displaced decays into $b$-jets in regions of parameter space where the SM-like Higgs and the twin Higgs do not provide any striking signatures.
