Resumo: Results on two-particle angular correlations for charged particles emitted in pp collisions at a center-of-mass energy of 13 TeV are presented as a function of charged-particle multiplicity and transverse momentum (pT). In high-multiplicity events, a long-range (|η| > 2.0), near-side (Δφ = 0) structure emerges in the two-particle Δη-Δφ correlation functions. The overall correlation strength is similar to that found in earlier pp data at 7 TeV, but is measured up to much higher multiplicity values. A detailed study in pp collisions at 7 TeV of the second-order (v2) azimuthal anisotropy harmonics of charged particles, KS 0 and Λ/Λ particles are extracted from long-range two-particle correlations as a function of particle multiplicity and transverse momentum, and are also compared with values obtained in pPb and PbPb collisions at similar multiplicities.
