| Measurements of two-and multi-particle angular correlations in pp collisions at s= 5, 7, and 13 TeV are presented as a function of charged-particle multiplicity. The data, corresponding to integrated luminosities of 1.0 pb− 1 (5 TeV), 6.2 pb− 1 (7 TeV), and 0.7 pb− 1 (13 TeV), were collected using the CMS detector at the LHC. The second-order (v 2) and third-order (v 3) azimuthal anisotropy harmonics of unidentified charged particles, as well as v 2 of K S 0 and Λ/Λ‾ particles, are extracted from long-range two-particle correlations as functions of particle multiplicity and transverse momentum. For high-multiplicity pp events, a mass ordering is observed for the v 2 values of charged hadrons (mostly pions), K S 0, and Λ/Λ‾, with lighter particle species exhibiting a stronger azimuthal anisotropy signal below p T≈ 2 GeV/c. For 13 TeV data, the v 2 signals are also extracted from four-and six-particle correlations for the first … |
