摘要

在这篇文章中，我们讨论了双希格斯-双重态模型(2HDM)类型-1和类型- x中的轻荷希格斯特征。我们通过考虑几个理论约束来确定允许的区域，包括电弱精度和味观测值，以及来自希格斯数据Run-2和LHC Run-2未观测到的额外希格斯的实验约束。我们提出的场景表明，根据2HDM参数的假设，2HDM中1型和x型带电希格斯粒子的产生和衰变是互补的。此外，我们发现，在约95 GeV的非标准中性希格斯玻色子的大范围参数空间中，轻荷希格斯玻色子的衰变会发生显著变化。

Probing light charged Higgs at the LHC Run 2

In this contribution we discuss light charged Higgs signatures in two-Higgs-doublet-model (2HDM) type-1 and type-X. We determine the allowed regions by including several theoretical constraints including elctroweak precision and flavour observables as well as experimental constraints coming from Higgs data Run-2 and from non-observed additional Higgs at Run-2 of LHC. Our proposal scenarios shows that the production and decay of charged Higgs in 2HDM type-1 and type-X are complementary depending on the assumptions of the 2HDM parameters. Additionally, we find that in a wide range of parameter space in which non-standard neutral Higgs boson $h$ of about 95 GeV can change dramatically the decay of light charged Higgs.
