Two-particle angular correlations in pp collisions recorded with the ALICE detector at the LHC

Abstract

We report on the studies of two-particle angular correlations measured in proton-proton collisions at a center-of-mass energy of √s = 7 TeV recorded by ALICE at the LHC. Two-particle correlations in relative azimuth (Δφ) and pseudorapidity (Δη) are expected to exhibit several structures which arise from different physics mechanisms and allow us to study the wide landscape of correlations. The results include the dependence of the correlation function on the event multiplicity, the charge combination and species (pions, kaons or protons) of particles in the pair.
