Description
Measurements of the ridge correlations and associated first five azimuthal harmonics (v1-v5) in 5.02 TeV p+Pb collisions using the two-particle correlations (2PC) method are presented. The vn results are shown as a function of pT, η and event activity. The non-zero double-ridge structures and vn are found to exist up to pT of ~10 GeV. In addition, the status of high statistics measurements of v2 (pT) in p+Pb and in peripheral 2.76 TeV Pb+Pb collisions obtained from multi-particle cumulant analysis is reported. A comparison between p+Pb and Pb+Pb results at matching event activity is performed, showing similarities of the two collision systems.
