摘要：
We compute the mid-rapidity densities of pions, kaons, baryons and antibaryons in Au-Au collisions at roots = 130 GeV in the dual parton model supplemented with final state interaction (comovers interaction). The ratios B/n(part) ((B) over bar /n(part)) increase between peripheral (n(part) = 18) and central (n(part) = 350) collisions by a factor 2.4 (2.0) for the Lambda, 4.8 (4.1) for the Xi and 16.5 (13.5) for the Omega. The ratio K-/pi(-) increases by a factor 1.3 in the same centrality range. A comparison with the available data is presented.
