用ATLAS探测器寻找Higgs和$Z$玻色子衰变到$ϕ\,γ$

Search for Higgs and $Z$ Boson Decays to $ϕ\,γ$ with the ATLAS Detector

ATLAS Collaboration

摘要:

用ATLAS探测器在LHC收集的$\sqrt{s}=$ 13 TeV的$pp$碰撞数据样本进行了Higgs和$Z$玻色子衰变为$ϕ$介子和光子的研究。没有观察到显着过量的事件以上的背景,和95%的置信水平上限的分支分数的希格斯和$Z$玻色子衰变到$ϕ\,γ$的1.4 $\times$ 10 $^{-3}$和8.3 $\times$ 10 $^{-6}$,分别获得。

英文摘要:

A search for the decays of the Higgs and $Z$ bosons to a $ϕ$ meson and a photon is performed with a $pp$ collision data sample corresponding to an integrated luminosity of 2.7 fb$^{-1}$ collected at $\sqrt{s}=$13 TeV with the ATLAS detector at the LHC. No significant excess of events is observed above the background, and 95% confidence level upper limits on the branching fractions of the Higgs and $Z$ boson decays to $ϕ\,γ$ of 1.4$\times$10$^{-3}$ and 8.3$\times$10$^{-6}$, respectively, are obtained.
