标题： Centrality dependence of multiplicities in ultrarelativistic nuclear collisions

摘要： 我们计算了在不同能量和原子序数下，超相对论核碰撞中产生的粒子的多重性与中心度的关系。 计算是在微扰QCD中进行的，考虑了产生胶子的饱和密度以及核几何效应。 给出了在RHIC能量下Au+Au碰撞的数值。 显示英文摘要

摘要： We compute the centrality dependence of multiplicities of particles produced in ultrarelativistic nuclear collisions at various energies and atomic numbers. The computation is carried out in perturbative QCD with saturated densities of produced gluons and by including effects of nuclear geometry. Numbers are given for Au+Au collisions at RHIC energies.
