| 英文摘要 | The fourier coefficients v(2) and v(3) characterizing the anisotropy of the azimuthal distribution of charged particles produced in pbpb collisions at root s-nn = 5.02 tev are measured with data collected by the cms experiment. the measurements cover a broad transverse momentum range, 1 < p(t) < 100 gev/c. the analysis focuses on the p(t) > 10 gev/c range, where anisotropic azimuthal distributions should reflect the path-length dependence of parton energy loss in the created medium. results are presented in several bins of pbpb collision centrality, spanning the 60% most central events. the v(2) coefficient is measured with the scalar product and the multiparticle cumulant methods, which have different sensitivities to initial-state fluctuations. the values from both methods remain positive up to p(t) similar to 60-80 gev/c, in all examined centrality classes. the v(3) coefficient, only measured with the scalar product method, tends to zero for p(t) greater than or similar to 20 gev/c. comparisons between theoretical calculations and data provide new constraints on the path-length dependence of parton energy loss in heavy ion collisions and highlight the importance of the initial-state fluctuations.
