Abstract
Interactions between jets and the quark-gluon plasma produced in heavy ion collisions are studied via the angular distributions of summed charged-particle transverse momenta (p[subscript T]) with respect to both the leading and subleading jet axes in high-p[subscript T] dijet events. The contributions of charged particles in different momentum ranges to the overall event p[subscript T] balance are decomposed into short-range jet peaks and a long-range azimuthal asymmetry in charged-particle p[subscript T]. The results for PbPb collisions are compared to those in pp collisions using data collected in 2011 and 2013, at collision energy √sNN = 2.76 TeV with integrated luminosities of 166 μb[superscript −1] and 5.3 pb[superscript −1], respectively, by the CMS experiment at the LHC. Measurements are presented as functions of PbPb collision centrality, charged-particle p[subscript T], relative azimuth, and radial distance from the jet axis for balanced and unbalanced dijets. Keywords: Jet substructure, Heavy Ion Experiments, Heavy-ion collision, Quark gluon plasma
