Nuclear effects in high-pT production of direct photons and neutral mesons

We present results on the production of direct photons, {pi}{sup 0}, and {eta} mesons on nuclear targets at large transverse momenta (p{sub T}). The data are from 530 and 800 GeV/c proton beams and 515 GeV/c {pi}{sup -} beams incident upon copper and beryllium targets that span the kinematic range of 1.0<p{sub T} < or approx. 10 GeV/c at central rapidities.
