论文摘要

观察光或重型带电的希格斯玻色子$ h^\ pm $,比顶级夸克更轻或重,将是超出标准模型的物理学的即时证据。因此,近年来,搜索被带电的希格斯玻色子的搜索一直处于当前山脉(例如CERN大型强子对撞机(LHC))的关注中心。尽管有所有努力,但尚未观察到任何信号。特别是,CMS和ATLAS实验的结果排除了MSSM $ M_ {H^+} - \TANβ$参数空间的$ M_ {H^+} = 80-160 $ GEV对应于$ \tanβ$ 60的整个范围。 ($ m_ {h^\ pm}> m_t $)因此,在此上下文中,每个新的探测通道都受到欢迎。在这项工作中,我们打算通过研究在带电的Higgs decay中包含的底味的介子($ b $)的缩放能量分布(即$ h^+\ to t \ bar {b} \ b+x $)。我们的研究是在通用两个Higgs Doublet模型(2HDM)的框架内使用无质量方案进行的,其中为底部夸克采用了零质量的部分近似值。

Observing light or heavy charged Higgs bosons $H^\pm$, lighter or heavier than the top quark, would be instant evidence of physics beyond the Standard Model. For this reason, in recent years searches for charged Higgs bosons have been in the center of attention of current colliders such as the CERN Large Hadron Collider (LHC). In spite of all efforts, no signal has been yet observed. Especially, the results of CMS and ATLAS experiments have excluded a large region in the MSSM $m_{H^+}-\tanβ$ parameter space for $m_{H^+}=80-160$ GeV corresponding to the entire range of $\tanβ$ up to 60. Therefore, it seems that one should concentrate on probing heavy charged Higgs bosons ($m_{H^\pm}>m_t$) so in this context each new probing channel is welcomed. In this work, we intend to present our proposed channel to search for heavy charged Higgses through the study of scaled-energy distribution of bottom-flavored mesons ($B$) inclusively produced in charged Higgs decay, i.e., $H^+\to t\bar{b}\to B+X$. Our study is carried out within the framework of the generic two Higgs doublet model (2HDM) using the massless scheme where the zero mass parton approximation is adopted for bottom quark.
