Study of direct-photon and pion production

Abstract

We present comparisons of high-pT photon and pion production in hadronic interactions with expectations from next-to-leading order perturbative QCD (NLO pQCD). We also comment on phenomenological models of kT smearing (which approximate effects of additional soft-gluon emission) and on the status of resummation calculations.
