Observation of nuclear modification of energy-energy correlators inside jets in heavy ion collisions / CMS Collaboration
Energy-energy correlators are constructed by averaging the number of charged particle pairs within jets, weighted by the product of their transverse momenta, as a function of the angular separation of the particles within a pair. [...]

Small-$ x $ evolution of gluon fields from incoherent $ \mathrm{J}/\psi $ photoproduction in ultraperipheral PbPb collisions / CMS Collaboration
Incoherent $ \mathrm{J}/\psi $ photoproduction in heavy ion ultraperipheral collisions (UPCs), in which the photon interacts with localized, fluctuating gluonic hotspots rather than the entire nucleus, provides a unique probe of those fluctuations. [...]
