摘要:

我们考虑了带电希格斯玻色子$pp\rightarrow H^{\pm}h\rightarrow W^{\pm}hh$的新特征,它几乎是无背景的,作为在LHC上用$\sqrt{s} = 13$ TeV和$\sqrt{s}= 14$ TeV研究超对称性的希望。在MSSM模型的框架下,我们采用了最新的理论参数空间,这与大型强子对撞机的实验约束和直接或间接的搜索是一致的。在Pythia 8.3和Feynhiggs程序的帮助下,发现在基准点4和基准点14处,产生截面$σ(pp\rightarrow H^{\pm}h)$和分支比$BR(H^{\pm}\rightarrow W^{\pm}h)$相应地最大。

英文摘要:

We considered the new signature of a charged Higgs boson, $pp\rightarrow H^{\pm}h\rightarrow W^{\pm}hh$, which is almost background free as the promising to study of supersymmetry at the LHC with both $\sqrt{s} = 13$ TeV and $\sqrt{s}= 14$ TeV. In the framework of MSSM model we used the latest theoretical parameter space, which is consistent with the experimental constraints from Large Hadron Collider and direct or indirect searches. In the surviving regions with the help of Pythia 8.3 and Feynhiggs programs it was found that production cross sections, $σ(pp\rightarrow H^{\pm}h)$, and Branching Ratios, $BR(H^{\pm}\rightarrow W^{\pm}h)$, are the largest at Benchmark Points 4 and 14 correspondingly.
