Transverse momentum distributions and their forward-backward correlations in the percolating color string approach
The forward-backward correlations in the p(T) distributions at midrapidity, which present a clear signature of nonlinear effects in particle production, are studied in the model of percolating color strings. Quantitative predictions are given for these correlations at SPS, RHIC, and LHC energies. Interaction of strings also naturally explains the flattening of p(T) distributions and increase of...
متن کامل2 v 1 1 3 Ju l 1 99 9 Implications of percolation of colour strings on multiplicities , correlations and the transverse momentum
In the colour string model the impact of string percolation on multiplicities, p 2 T and their long range (forward-backward) correlations is studied. It is assumed that different string overlaps produce the observed hadrons independently. The multiplicities are shown to be damped by a simple factor which follows from the percolation theory. The p 2 T rise at the same rate as multiplicities fall...
متن کاملTransverse momentum fluctuations and percolation of strings
The peculiar behaviour of the transverse momentum fluctuations with the centrality of the collision shown by the Relativistic Heavy Ion Collider data is naturally explained by the percolation of strings. In this framework, the pT fluctuations are nothing but fluctuations on the number of overlapping strings that form clusters in a heavy ion collision. According to this idea, the fluctuations sh...
متن کاملTransverse Momentum Correlations in Production Processes*
A simple method to analyze two-particle correlations of transverse momenta in multiparticle final states is described. A clear physical interpretation of such correlations is presented, and a preliminary analysis of several reactions involving three and four body final states is reported. (Submitted to Phys . Rev.) * Work supported by the U. S. Atomic Energy Commission. Increasing machine energ...
متن کاملEstimation of shear viscosity based on transverse momentum correlations
Event anisotropy measurements at RHIC suggest the strongly interacting matter created in heavy ion collisions flows with very little shear viscosity. Precise determination of “shear viscosityto-entropy” ratio is currently a subject of extensive study [1]. We present preliminary results of measurements of the evolution of transverse momentum correlation function with collision centrality of Au +...
