论文摘要
我们提出了对CMS协作现有结果的重新解释研究，具体来说，在链衰减中产生的标准模型（BSM）Higgs对higgs $ pp \ to h _ {\ rm sm} \ to hh（aa）$ to cp-conserving 2-higgggsi-2 dombles（2 domble）（2 domble）（2 domble）（2 domble）（2 domble）（2 domble）（2 domble）（2 domber）（aa）中产生的光。通过此，我们将大型强子对撞机（LHC）的灵敏度测试到可能的新签名，$ pp \ to h _ {\ rm sm} \ to za \ to zz h $，并带有$ zz \ tojjμ^+μ^ - $^ - $^ - $和$ h \ to b \ bar b $。我们通过考虑所有可用的理论和实验约束，在2HDM I型参数空间上进行系统的扫描，以找到具有潜在可见信号的区域。我们通过完整的蒙特卡洛模拟调查了它的重要性，直到参数化的检测器水平。我们表明，这样的信号是已经在LHC处的标准四体搜索的标准四体搜索的替代有希望的通道，其集成的光度为$ {\ cal l} = 300〜 {\ rm fb}^{ - 1} $。对于后者的十倍增加，应该在大多数允许的参数空间中进行发现。
We present a reinterpretation study of existing results from the CMS Collaboration, specifically, searches for light Beyond the Standard Model (BSM) Higgs pairs produced in the chain decay $pp\to H_{\rm SM}\to hh(aa)$ into a variety of final states, in the context of the CP-conserving 2-Higgs Doublet Model (2HDM) Type-I. Through this, we test the Large Hadron Collider (LHC) sensitivity to a possible new signature, $pp\to H_{\rm SM}\to ZA\to ZZ h$, with $ZZ\to jj μ^+μ^-$ and $h\to b\bar b$. We perform a systematic scan over the 2HDM Type-I parameter space, by taking into account all available theoretical and experimental constraints, in order to find a region with a potentially visible signal. We investigate the significance of it through a full Monte Carlo simulation down to the parametrised detector level. We show that such a signal is an alternative promising channel to standard four-body searches for light BSM Higgses at the LHC already with an integrated luminosity of ${\cal L} = 300~{\rm fb}^{-1}$. For a tenfold increase of the latter, discovery should be possible over most of the allowed parameter space.
