论文摘要
结果是从proton-proton碰撞中的标准模型以外的物理搜索以$ \ sqrt {s} = $ 13的通道中带有两个Higgs玻色子的$ 13 TEV来提出的，每个TEV都会通过过程h $ \ $ \ $ \ $ \ mathrm {b \ bar {b \ bar {b}} $，以及大缺少的横向动量。该搜索使用与CMS实验在CERN LHC收集的137 fb $^{ - 1} $的集成光度相对应的数据样本。搜索是由超对称模型的动机，这些模型预测了中性诺斯（Electroweak Gauge）和希格斯（Higgs）玻色子的中性伴侣的产生。发现信号区域中观察到的事件产量与标准模型背景期望一致。使用超对称的简化模型来解释结果。为了产生几乎质量化的希格斯诺诺斯（Higgsinos），其每个腐烂链都会产生中性链（$ \ \tildeχ^0_1 $），从而落到了无质量的Goldstino和Higgs Boson和Higgs Boson，$ \tildeχ^0_1 $中，在175至1025 geev的范围内，将其排除在95％的范围内。对于Gluino对的强大生产，通过略微较轻的$ \tildeχ^0_2 $腐烂到H和轻度$ \tildeχ^0_1 $，Gluino Masses低于2330 GEV。
Results are presented from a search for physics beyond the standard model in proton-proton collisions at $\sqrt{s} =$ 13 TeV in channels with two Higgs bosons, each decaying via the process H $\to$ $\mathrm{b\bar{b}}$, and large missing transverse momentum. The search uses a data sample corresponding to an integrated luminosity of 137 fb$^{-1}$ collected by the CMS experiment at the CERN LHC. The search is motivated by models of supersymmetry that predict the production of neutralinos, the neutral partners of the electroweak gauge and Higgs bosons. The observed event yields in the signal regions are found to be consistent with the standard model background expectations. The results are interpreted using simplified models of supersymmetry. For the electroweak production of nearly mass-degenerate higgsinos, each of whose decay chains yields a neutralino ($\tildeχ^0_1$) that in turn decays to a massless goldstino and a Higgs boson, $\tildeχ^0_1$ masses in the range 175 to 1025 GeV are excluded at 95% confidence level. For the strong production of gluino pairs decaying via a slightly lighter $\tildeχ^0_2$ to H and a light $\tildeχ^0_1$, gluino masses below 2330 GeV are excluded.
