    "abstract": "We investigate the centrality dependence of the pT-correlations in the\nevent-by-event analysis of relativistic heavy-ion collisions at RHIC made\nrecently by the PHENIX and STAR Collaborations. We notice that sigma^2\ndynamical scales to a very good accuracy with the inverse number of the\nproduced particles, n. This scaling can be naturally explained by formation of\nclusters. We discuss the nature of clusters and provide numerical estimates of\ncorrelations coming from resonance decays, which are tiny, and a model where\nparticle are emitted from local thermalized sources moving at the same\ncollective velocity. This \"lumped cluster\" model can explain the data when on\nthe average 6-15 particles are contained in a cluster. We also point out simple\nrelations of the popular correlation measures to the covariance, which arise\nunder the assumptions (well holding at RHIC) that the distributions are sharply\npeaked in n and that the dynamical compared to statistical fluctuations are\nsmall.",
