Background: Numerous studies have investigated the relevance of callous-unemotional traits in relation to externalizing psychopathology among children and adolescents. However, less research has examined the connections between callous-unemotional traits and internalizing psychopathology and findings were inconsistent. Consequently, the present study aimed to elucidate the role of callous-unemotional traits in the context of depression and anxiety while controlling for conduct problems, age, and gender.

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 sqrt[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.

The data are compatible with the predicted background. For the first time, an upper limit at the 95% confidence level of 6.
