#CMSPaper 1228: one of the #unexpected #discoveries by CMS is correlations between the particles in proton-proton collisions, and this paper measures those in more detail by comparing short-range to long-range particle charges in various LHC collisions http://arxiv.org/abs/2307.11185 CMS Collaboration #CERN #physics #highenergynuclearphysics #ridge #particles #heavyionphysics

#CMSPaper 1198: D mesons are two-quark particles that contain one charm quark. In this paper, the behavior of D mesons produced directly in a lead-lead collision is compared to D mesons from b quark decays, both when traversing the #quarkgluonplasma. The conclusion: charm quarks get stopped less by the QGP than bottom quarks! http://cms-results.web.cern.ch/cms-results/public-results/publications/HIN-21-003/index.html #heavyionphysics #physics #cern @CMSexperiment
