Description
The elliptic and triangular azimuthal anisotropies of charged particles produced in PbPb collisions at sqrt(s_NN) = 5.02 TeV are measured with the CMS detector at the LHC over an extended transverse momentum (p_T) range up to approximately 100 GeV/c. The data cover both the low-p_T (~ 1 GeV/c) region associated with hydrodynamic flow phenomena and the high-pT region where anisotropic azimuthal distributions may reflect the path-length dependence of parton energy loss in the created medium. Several methods were used to extract the anisotropy Fourier coefficients, such as the scalar product and multi-particle cumulant methods. The data are compared to theoretical calculations involving parton energy loss in a dense QCD medium.
