Abstract

We present results on the production of high transverse momentum π0 and η mesons in π-p and π-Be interactions at 515 GeV/c. The data span the kinematic ranges 1 <p T< 11 GeV/c in transverse momentum and -.0.75≤y m≤0.75 in rapidity. The inclusive π0 cross sections are compared with next-to-leading order QCD calculations and to expectations based on a phenomenological parton-k model.
