Аннотация: The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosityof 138 fb−1 of proton-proton collision data at √s = 13 TeV, collected in 2016–2018 by the CMS detectorat 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, themultiplicity and sphericity of clustered tracks are used to reject the background from standard modelquantum chromodynamics. With no observed excess of events over the standard model expectation, limitsare set on the cross section for production via gluon fusion of a scalar mediator with SUEP-like decays.
