纹理化双希格斯偶态模型（2 HDM-Tx）中的味道破坏希格斯信号
Flavor Violating Higgs signals in the Texturized Two-Higgs Doublet Model (2HDM-Tx)
摘要：
在大型强子对撞机上研究了味道破坏的Higgs信号，如顶FCNC衰变$t\to ch^0$和LFV Higgs衰变$h^0\to τμ$。这些信号可以出现在一般的双希格斯二重态模型（THDM）中，其中每个希格斯二重态通过汤川矩阵$Y^f_1$和$Y^f_2$与所有费米子类型耦合。可以假设Yukawa矩阵具有相同的形式，或者它们可以具有不同的结构。在本文中，我们研究的情况下，当$Y^f_1$和$Y^f_2$有完全不同的形式，但在这样一种方式，他们补充产生一个特定的厄米质量矩阵。我们发现，对于特定的四零织构，违反味道的希格斯耦合只依赖于自由参数$\tan β$，$γ_f$和费米子质量。我们使用当前的低能量过程的界限，推导出重希格斯玻色子的质量，$\tan β$和$γ_f$的约束。然后，我们使用这些限制来评估LFV希格斯衰变，达到分支比，可以在大型强子对撞机测试。
英文摘要：
Flavor violating Higgs signals, such as the top FCNC decay $t\to ch^0$ and the LFV Higgs decay $h^0\to τμ$, have been studied at the LHC. These signals can arise within the general Two-Higgs doublet model (THDM), where each Higgs doublet couples to all fermions types through Yukawa matrices $Y^f_1$ and $Y^f_2$. The Yukawa matrices can be assumed to have the same form or they could have different structures. In this paper we study the case when both $Y^f_1$ and $Y^f_2$ have completely different forms, but in such a way that they complement to produce a specific hermitian mass matrix. We find that for specific four-zero textures, the Flavor Violating Higgs couplings depend only on the free parameters $\tan β$, $γ_f$ and the fermion masses. We use the current bounds on the low energy processes, to derive constraints on the Heavy Higgs boson mass, $\tan β$ and $γ_f$. Then, we use these constraints to evaluate the LFV Higgs decays, which reach Branching ratios that could be tested at the LHC.
