具有反跷跷板机构的$ν$ THDM

The $ν$THDM with the Inverse Seesaw Mechanisms

Yi-Lei Tang, Shou-hua Zhu

摘要:

本文将$ν$ -Two-Higgs-Doublet-Model($ν$ THDM)与反跷跷板机制相结合。在这个模型中,在大的$\tan β$情况下,涉及不育中微子和奇异希格斯玻色子的汤川耦合可以是一阶的。计算了Z共振参数$R_{l_i}$、$A_{l_i}$、$N_ν$的修正值,以及$l_1 \rightarrow l_2 γ$分支比和μ子反常$g-2$。与现有的边界和未来对撞机的计划相比,我们发现对电弱参数的修正可以在大部分参数空间中被约束或发现。

英文摘要:

In this paper, we combine the $ν$-Two-Higgs-Doublet-Model ($ν$THDM) with the inverse seesaw mechanisms. In this model, the Yukawa couplings involving the sterile neutrinos and the exotic Higgs bosons can be of order one in the case of a large $\tan β$. We calculated the corrections to the Z-resonance parameters $R_{l_i}$, $A_{l_i}$, $N_ν$, together with the $l_1 \rightarrow l_2 γ$ branching ratios, and the muon anomalous $g-2$. Compared with the current bounds and plans for the future colliders, we find that the corrections to the electroweak parameters can be contrained or discovered in much of the parameter space.
