论文摘要
我们通过谐振过程x $ \ to $ yh $ \ to $ \ $ \ mathrm {b \ bar {b} b \ bar {b}} $搜索新的大型标量粒子x和y，其中H是标准的模型Higgs higgs boson。使用CERN LHC Proton-Proton碰撞的数据，在2016 - 2018年以13 TEV的中心能量收集，对应于138 fb $^{ - 1} $的集成发光度。搜索以X的质量范围为0.9-4 TEV，Y进行了60-600 GEV，其中Y和H均以lorentz增强的单个大面积喷头重建。结果是在近代到最小的超对称标准模型的背景下进行解释的，并且在标准模型的扩展中，并具有两个附加的单元标量表字段。生产横截面的95％置信水平上限在0.1至150 fb之间变化，具体取决于X和Y质量，并且比以前搜索的结果有了显着改善。
We search for new massive scalar particles X and Y through the resonant process X $\to$ YH $\to$ $\mathrm{b\bar{b}b\bar{b}}$, where H is the standard model Higgs boson. Data from CERN LHC proton-proton collisions are used, collected at a centre-of-mass energy of 13 TeV in 2016-2018 and corresponding to an integrated luminosity of 138 fb$^{-1}$. The search is performed in mass ranges of 0.9-4 TeV for X and 60-600 GeV for Y, where both Y and H are reconstructed as Lorentz-boosted single large-area jets. The results are interpreted in the context of the next-to-minimal supersymmetric standard model and also in an extension of the standard model with two additional singlet scalar fields. The 95% confidence level upper limits for the production cross section vary between 0.1 and 150 fb depending on the X and Y masses, and represent a significant improvement over results from previous searches.
