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_{T}) ) with respect to both the leading and subleading jet axes in high- (p_{T}) dijet events. The contributions of charged particles in different momentum ranges to the overall event (p_{T}) balance are decomposed into short-range jet peaks and a long-range azimuthal asymmetry in charged-particle (p_{T}). The results for PbPb collisions are compared to those in pp collisions using data collected in 2011 and 2013, at collision energy (\sqrt{s_{\mathrm{NN}}})=2.76TeVwith integrated luminosities of 166 μb(^{−1}) and 5.3 pb(^{−1}), respectively, by the CMS experiment at the LHC. Measurements are presented as functions of PbPb collision centrality, charged-particle (p_{T}), relative azimuth, and radial distance from the jet axis for balanced and unbalanced dijets.
