2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/195857We present results on the production of direct photons, pizero, and eta mesons on nuclear targets at large transverse momenta (p_T). The data are from 530 and 800 GeV/c proton beams and 515 GeV/c piminus beams incident upon copper and beryllium targets that span the kinematic range of 1.0 < p_T < 10 GeV/c at central rapidities.RevTeX4, 15 pages, 23 figures, submitted to Phys.
