Abstract

Short-range correlations of identified charged hadrons in pp (s = 0.9, 2.76, and 7 TeV), pPb (√s NN = 5.02 TeV), and peripheral PbPb collisions (√s NN = 2.76 TeV) are studied with the CMS detector at the LHC. Charged pions, kaons, and protons at low momentum and in laboratory pseudorapidity |η| < 1 are identified via their energy loss in the silicon tracker. The two-particle correlation functions show effects of quantum statistics, Coulomb interaction, and also indicate the role of multi-body resonance decays and mini-jets. The characteristics of the one-, two-, and three-dimensional correlation functions are studied as a function of transverse pair momentum, k T , and the charged-particle multiplicity of the event. The extracted radii are in the range 1-5 fm, reaching highest values for very high multiplicity pPb, also for similar multiplicity PbPb collisions, and decrease with increasing k T . The dependence of radii on multiplicity and k T largely factorizes and appears to be insensitive to the type of the colliding system and center-of-mass energy.
