Production of π0 and η mesons at large transverse momenta in π-p and π-Be interactions at 515 GeV/c
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<pT<11 GeV/c in transverse momentum and -0.75⩽ycm⩽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-kT model.
