Ma. Braun et C. Pajares, Transverse momentum distributions and their forward-backward correlations in the percolating color string approach, PHYS REV L, 85(23), 2000, pp. 4864-4867
The forward-backward correlations in the p(T) distributions at midrapidity,
which present a clear signature of nonlinear effects in particle productio
n, are studied in the model of percolating color strings. Quantitative pred
ictions are given for these correlations at SPS, RHIC, and LHC energies. In
teraction of strings also naturally explains the flattening of p(T) distrib
utions and increase of (p(T)) with energy and atomic number for nuclear col
lisions.
