2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/227404We present results on the production of high transverse momentum pizero and eta mesons in pi-p and pi-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 < 0.75 in rapidity. The inclusive pizero cross sections are compared with next-to-leading order QCD calculations and to expectations based on a phenomenological parton-k_T model.RevTeX4, 15 pages, 15 figures, to be submitted to Phys.
