| Abstract: | We compute the leading baryon spectrum in high-energy nuclear collisions in the framework of the Dual parton model. Nucleus-nucleus collisions are treated in full detail. The average rapidity shift of the leading baryon (nuclear stopping power) is studied as a function of the degree of centrality of the collision and the cross-section of the selected events is given. Important differences are found here between proton-nucleus and nucleus-nucleus interactions. The agreement with existing data on proton-nucleus and α?α collisions is quite good. |
