    "abstract": "The scaling of pion multiplicities with system size in proton-nucleus and\nnucleus-nucleus reactions at 200 A GeV is investigated. A nuclear geometry\ncalculation of incoherent multiple scattering including effects of deceleration\nof the participating particles is presented. Pion multiplicities at high\ntransverse momenta agree relatively well with an overall scaling with the\nnumber of binary collisions. The deviations from this gross scaling for p+A and\nS+Au reactions at 200AGeV are compared to model predictions and the\nimplications are discussed. Within this picture no universal scaling law for\nhigh pT particle production is obtained. In addition to the conceptual problems\nof such an incoherent model, it is shown that the implied kinematic relation\nbetween a possible pT-broadening and deceleration leads to contradictions. The\nscaling of pion production at intermediate pT with system size does not\nindicate a multiple scattering enhancement.",
