Nonlinear response coefficients of higher-order vn anisotropy harmonics for charged particles, as a function of transverse momentum (pT) and collision centrality, are measured in PbPb collisions at sNN = 2.76 and 5.02 TeV. The nonlinear response coefficients are obtained using vn harmonics measured with respect to their own plane and the mixed harmonics. The results are compared with hydrodynamic models with different shear viscosity to entropy density ratios and initial conditions. Additionally, the v2 and v3 anisotropy harmonics of charged particles and prompt D0 mesons are measured at |y|≤1 as a function of pT and centrality in PbPb data at sNN = 5.02 TeV collected with the CMS detector. Prompt D0 mesons, formed from the c quarks produced via initial hard scatterings, are separated up to a high extent from nonprompt D0 mesons emerged from decays of b hadrons. The results indicate that the charm quarks interact strongly with the QGP medium. Comparisons between theoretical models and ...data provide new constraints on the interaction between charm quarks and the QGP medium. © Copyright owned by the author(s).
