Description

The extent of a locally equilibrated parton plasma in d+Au collisions at √sNN = 200 GeV is investigated as a function of centrality in a nonequilibrium-statistical framework. Based on a three-sources model, analytical solutions of a relativistic diffusion equation are in precise agreement with recent data for charged-particle pseudorapidity distributions. The moving midrapidity source indicates the size of the local thermal equilibrium region after hadronization. In central d+Au collisions it contains 19% of the produced particles. (author)
