使用大型强子对撞机（LHC）上CMS实验的数据搜索流收集的、质心能量为13 TeV、积分亮度为127 fb⁻¹的质子-质子碰撞数据，开展对软非聚集能量模式（SUEP）的搜索。仅记录高级触发重建结果以降低强子活动阈值，提高对SUEP信号的接受度，该信号由具有大‘t Hooft耦合的隐谷模型预测。观测结果与标准模型背景预测一致，对导致类似SUEP信号的重标量媒介子的胶子融合产生设置了迄今为止最严格的限制。
英文摘要
A search for soft unclustered energy patterns (SUEPs) is conducted using proton-proton collision data corresponding to an integrated luminosity of 127 fb$^{-1}$ at a center-of-mass energy of 13 TeV, collected via the data scouting stream of the CMS experiment at the LHC. Only the results of the high-level trigger reconstruction are recorded to enable a lower threshold on the hadronic activity. This increases the acceptance for SUEP signatures, which are predicted by hidden-valley models with a large 't Hooft coupling. The observed results are consistent with the standard model background prediction. The most stringent limits to date are set on the gluon fusion production of heavy scalar mediators resulting in SUEP-like signals.
