在LHC运行2中发现真正的希格斯玻色子$H_T$的证据

Evidence of the true Higgs boson $H_T$ at the LHC Run 2

Paolo Cea

摘要:

本说明的目的是比较最近的大型强子对撞机数据在$\sqrt{s} =13 \,TeV$与我们以前的理论建议,真正的希格斯玻色子$H_T$应该是一个广泛的重共振周围的质量$750 \, GeV$。我们专注于所谓的黄金通道$H_T \rightarrow ZZ$的Z玻色子对轻子衰变到$\ell^+ \ell^- \ell^+ \ell^-$,$\ell$是一个电子或μ子。我们使用的数据收集的ATLAS和CMS合作在$\sqrt{s} =13 \,TeV$与$36.1 \, fb^{-1}$和$77.4 \, fb^{-1}$的综合光度分别。我们发现两个大型强子对撞机合作组的实验数据在黄金通道中确实显示了一个相当广泛的共振结构,在$700 \, GeV$周围具有相当大的统计意义。我们的理论预期似乎与实验观察相当吻合。结合ATLAS和CMS合作的数据,我们获得了在这个通道中存在重希格斯玻色子玻色子的证据,估计统计显著性超过5个标准差。

英文摘要:

The aim of the present note is to compare the recent LHC data at $\sqrt{s} =13 \,TeV$ with our previous theoretical proposal that the true Higgs boson $H_T$ should be a broad heavy resonance with mass around $750 \, GeV$. We focus on the so-called golden channel $H_T \rightarrow ZZ$ where the pair of Z bosons decay leptonically to $\ell^+ \ell^- \ell^+ \ell^-$, $\ell$ being either an electron or a muon. We use the data collected by the ATLAS and CMS Collaborations at $\sqrt{s} =13 \,TeV$ with an integrated luminosity of $36.1 \, fb^{-1}$ and $77.4 \, fb^{-1}$ respectively. We find that the experimental data from both the LHC Collaborations do display in the golden channel a rather broad resonance structure around $700 \, GeV$ with a sizeable statistical significance. Our theoretical expectations seem to be in fair good agreement with the experimental observations. Combining the data from both the ATLAS and CMS Collaborations we obtain an evidence of the heavy Higgs boson in this channel with an estimated statistical significance of more than five standard deviations.
