Bosonic Decays of Charged Higgs Bosons in a 2HDM Type-I

Abdesslam Arhrib, Rachid Benbrik, Stefano Moretti

摘要:

在本研究中,我们主要研究了在2-Higgs双重模型(2 HDM)中轻荷希格斯玻色子的玻色子衰变。我们量化的分支比(BR)的$H^\pm \to W^\pm h$和$H^\pm\to W^\pm A$通道,并表明它们可能是实质性的几个领域的参数空间的2 HDM类型-I仍然允许的大型强子对撞机(LHC)和其他实验数据以及理论约束。我们建议,$H^\pm \to W^\pm h$和/或$H^\pm \to W^\pm A$可以被用作替代$H^\pm \to τν$的可行的发现信道。

英文摘要:

In this study, we focus on the bosonic decays of light charged Higgs bosons in the 2-Higgs Doublet Model (2HDM) Type-I. We quantify the Branching Ratios (BRs) of the $H^\pm \to W^\pm h$ and $H^\pm\to W^\pm A$ channels and show that they could be substantial over several areas of the parameter space of the 2HDM Type-I that are still allowed by Large Hadron Collider (LHC) and other experimental data as well as theoretical constraints. We suggest that $H^\pm \to W^\pm h$ and/or $H^\pm \to W^\pm A$ could be used as a feasible discovery channel alternative to $H^\pm \to τν$.
