Abstract: (APS)

The authors have measured the large-pT inclusive cross sections for π0 and η production near 90° in the center-of-mass system in 200-GeV/c π+ and proton collisions with beryllium, carbon, and aluminum targets. The cross section for both π0 and η mesons rises with increasing nucleon number (A) of the target nucleus as Aα, with α>1. The ratio of the π0 yield in pA collisions to that in π+A collisions decreases with increasing pT.
