Nuclear effects in high-p_T production of direct photons and neutral   mesons
  We 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.
