论文摘要
最近，CMS协作报告了Di-Tau的过量，其局部意义为2.6-3.1 $σ$，其中不变质量为$ M_ {ττ} = $ 95-100 GEV。这种多余的可以解释为轻标量玻色子，将其与第三代费米子（尤其是顶部和$τ$）伴侣。基于可以说明CMS Di-Tau过量的最简单模型，我们使用ATLAS协作报告的结果评估了对其他光共振的实验敏感性。我们看到，搜索Sm Higgs玻色子的顶级相关生产，该玻色子衰减为$τ\barτ$设置了一个强大的模型独立限制。我们还发现，ATLAS结果不排除光共振的CP量表解释，而CP-ODD的解释不是。
Recently, the CMS collaboration has reported a di-tau excess with a local significance of 2.6-3.1$σ$ where the invariant mass is $m_{ττ}=$95-100 GeV. This excess can be interpreted as a light scalar boson that couples to the third generation fermions, particularly top and $τ$. Based on the simplest model that can account for the CMS di-tau excess, we evaluate experimental sensitivities to the additional light resonance, using the results reported by the ATLAS collaboration. We see that a search for the top-quark associated production of the SM Higgs boson that decays into $τ\barτ$ sets a strong model-independent limit. We also find that the CP-even scalar interpretation of the light resonance is excluded by the ATLAS results, while the CP-odd interpretation is not.
