The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb−1 of proton-proton collision data at √𝑠=13  TeV, collected in 2016–2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large ’t Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics. With no observed excess of events over the standard model expectation, limits are set on the cross section for production via gluon fusion of a scalar mediator with SUEP-like decays.

在 13 TeV 的质子-质子碰撞中搜索软非聚集能量模式


对软非聚集能量模式 （SUEP） 的首次搜索是使用 √s=13 TeV 的质子-质子碰撞数据的 138 fb-1 积分光度进行的，该数据由 LHC 的 CMS 探测器于 2016-2018 年收集。这种 SUEP 是由隐谷模型预测的，该模型具有一个新的、具有大 't Hooft 耦合的约束力。在由高阈值强子触发器选择的具有增强拓扑的事件中，簇轨迹的多重性和球形度用于拒绝来自标准模型量子色动力学的背景。由于没有观察到超过标准模型预期的事件，因此在横截面上设置了通过标量介质的胶子融合与 SUEP 样衰变产生的限制。
