Abstract
The baryon number transfer is studied in elementary and complex hadronic interactions at the CERN experiment NA49 at the SPS, at 158 AGeV beam energy (√s=17.2 GeV) A two-component picture is proposed, which builds up the net proton distribution from a target and a projectile component. Using pion beam, the projectile component is experimentally determined for p + p and p + A interactions. A similar stopping behaviour of the projectile component is found for p + A and A + A interactions. Based on these observations, the baryon transfer is assumed to provide a common scale of inelasticity in p + p, p + A and A + A interactions. A model-independent way is proposed to predict the pion multiplicity in A + A.
