摘要:

本文对在大型强子对撞机(LHC)的胶子融合过程$pp (gg+gq) \to h + jet \to τ^+ τ^- + jet$中探测到希格斯玻色子的可行性进行了详细的部分子水平研究。所得到的结果被应用到几个选定的超越标准模型(BSM)的情况下,一个希格斯玻色子衰变成一个$τ^+ τ^-$对的分支比增强相比,标准模型(SM)的情况。我们提出的参数空间的BSM的情况下,可以观察到在大型强子对撞机,并得出结论,参数空间的某些区域可以探测到只有几个$fb^{-1}$的积分亮度。值得注意的是,我们的研究结果的形式,这可能允许他们的应用程序产生的$pp (gg+gq) \to h + jet \to τ^+ τ^- + jet$签名的任何通用模型。

英文摘要:

We perform a detailed parton level study on the feasibility of the detection of a Higgs boson in the gluon fusion process $pp (gg+gq) \to h + jet \to τ^+ τ^- + jet$ at the Large Hadron Collider (LHC). The obtained results are applied to a few chosen Beyond the Standard Model (BSM) scenarios where the branching ratio of a Higgs boson decaying into a $τ^+ τ^-$ pair is enhanced as compared to the Standard Model (SM) case. We present the parameter space of the BSM scenarios that can be observed at the LHC and conclude that some regions of the parameter space can be probed with just a few $fb^{-1}$ of integrated luminosity. Noticeably, our results are presented in a form which potentially allows their application to any generic model giving rise to a $pp (gg+gq) \to h + jet \to τ^+ τ^- + jet$ signature.
