摘要:

我们更新的2-希格斯双重模型III型(2 HDM-III)的带电希格斯部门的味道违反约束,使用一个四零纹理的汤川矩阵。我们给出了2 HDM-III的一般拉格朗日量。为了显示这种纹理的非对角项的相关性,我们利用了来自$B$ -物理学的主要约束,$μ-e$在$τ$衰变中的普遍性以及最近在arXiv:1212.6818 [hep-ph]中提出的辐射衰变$Z\to b \bar{b}$。特别是,我们表明,$H^- c \bar{b}$耦合可以是非常大的和非常不同的2 HDM与风味离散对称(即,${\mathcal{Z}}_2$)。我们还讨论了可能的增强顶点$H^\pm W^\mp V$($V=Z, γ$)出现在一个循环的水平。

英文摘要:

We update the flavor-violating constraints on the charged Higgs sector of the 2-Higgs Doublet Model Type-III (2HDM-III), using a four-zero texture in the Yukawa matrices. We give a generic Lagrangian of the 2HDM-III. In order to show the relevance of the off-diagonal terms of such a texture, we utilize the main constraints from $B$-physics, $μ-e$ universality in $τ$ decays and the radiative decay $Z\to b \bar{b}$ presented recently in arXiv:1212.6818 [hep-ph]. In particular, we show that the $H^- c \bar{b}$ coupling can be very large and very different with respect to 2HDMs with a flavor discrete symmetry (i.e., ${\mathcal{Z}}_2$). We also discuss the possible enhancements of the vertices $H^\pm W^\mp V$ ($V=Z, γ$) that arise at one-loop level.
