论文摘要
我们提出了一种新型的搜索，以搜索通过外壳希格斯产生的伪级粒子$η$η$，$ pp \ to h^*\至η$。搜索是由复合Higgs模型激励的，其中$η$非常狭窄，并且在质量范围内几乎完全腐烂成$Zγ$ $ 65 $ GEV $ \ LISHSIMM_η\ Lessim 160 $ GEV。我们制定了一种分析策略，以观察新型$ZγZγ$通道并估算Higgs-$η$耦合的潜在范围。对特征的实验敏感性取决于识别假光子的功率以及预测大型光子多重性的能力。这种搜索使我们能够排除综合量表$ f $的大量价值，因此与其他典型过程互补。
We propose a new type of search for a pseudoscalar particle $η$ pair produced via an off-shell Higgs, $pp\to h^*\to ηη$. The search is motivated by a composite Higgs model in which the $η$ is extremely narrow and decays almost exclusively into $Zγ$ in the mass range $65$ GeV$\lesssim m_η\lesssim 160$ GeV. We devise an analysis strategy to observe the novel $ZγZγ$ channel and estimate potential bounds on the Higgs-$η$ coupling. The experimental sensitivity to the signatures depends on the power to identify fake photons and on the ability to predict large photon multiplicities. This search allows us to exclude large values of the compositeness scale $f$, being thus complementary to other typical processes.
