2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/227403We present results on the production of high transverse momentum pizero and eta mesons in pp and pBe interactions at 530 and 800 GeV/c. The data span the kinematic ranges: 1 < p_T < 10 GeV/c in transverse momentum and 1.5 units 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.RevTeX, 63 pages, 25 figures, to be submitted to Phys.
