在$\sqrt{s}=$ 13 TeV质子-质子碰撞中两个μ子和两个$τ$轻子的末态中希格斯玻色子到一对轻赝标量的奇异衰变的研究

Search for an exotic decay of the Higgs boson to a pair of light pseudoscalars in the final state of two muons and two $τ$ leptons in proton-proton collisions at $\sqrt{s}=$ 13 TeV

CMS Collaboration

摘要:

利用2016年在LHC的CMS实验中记录的质子-质子碰撞数据,在两个μ子和两个$τ$轻子的最终状态下,寻找奇异的希格斯玻色子衰变为轻赝标量,质心能量为13 TeV,对应于35.9 fb $^{-1}$的积分亮度。质量的赝标玻色子之间的15.0和62.5 GeV的探测,并没有显着过量的数据被观察到以上的标准模型的预测。在用复标量单线态扩展的不同类型的双Higgs偶态模型中,给出了希格斯玻色子玻色子到两个轻赝标玻色子的分支分数的上限.

英文摘要:

A search for exotic Higgs boson decays to light pseudoscalars in the final state of two muons and two $τ$ leptons is performed using proton-proton collision data recorded by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV in 2016, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. Masses of the pseudoscalar boson between 15.0 and 62.5 GeV are probed, and no significant excess of data is observed above the prediction of the standard model. Upper limits are set on the branching fraction of the Higgs boson to two light pseudoscalar bosons in different types of two-Higgs-doublet models extended with a complex scalar singlet.
