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.

我们研究了在13 TeV LHC的情况下，重标量超伙伴的电弱子的搜索。我们考虑了直接产生模式和与重希格斯玻色子玻色子衰变有关的模式，并集中讨论了轻希格斯玻色子和比诺斯玻色子的情况。在这种情况下，直接生产搜索变得比在轻度Wino场景中更具挑战性。在直接生产模式中，我们使用目前的实验搜索，以设置这些粒子在较大的光度范围，我们强调的相关性，考虑中性规范玻色子和中性希格斯衰变模式的第二和第三轻的中性伴子。我们显示了这些搜索的互补性与诱导的衰变的重希格斯玻色子玻色子，这是占主导地位的相关生产的最轻的中性伴子与第二和第三轻的，后者衰变成规范玻色子。我们表明，根据$\tanβ$的值，希格斯玻色子玻色子衰变通道仍然具有竞争力的直接生产通道重希格斯玻色子玻色子质量约1 TeV。此外，这种搜索不受直接产生模式中相同的运动学考虑的限制，并且可以覆盖质量达到较重的电弱伴子衰变为最轻的中性伴子的运动学阈值。这种衰变模式也提供了另一种在这个质量范围内寻找重希格斯玻色子玻色子的方法，因此应该是未来大型强子对撞机分析的高度优先事项。
