Standing Problem

The invariant cross sections for direct photon production in hadron-hadron collisions are calculated for several initial energies (SPS, ISR, [Formula: see text], RHIC, Tevatron, LHC) including initial parton transverse momenta within the formalism of unintegrated parton distributions (UPDF). Kwieciński UPDFs provide very good description of all world data, especially at SPS and ISR energies. Inclusion of the QCD evolution effects and especially their effect on initial parton transverse momenta allowed to solve the long-standing problem of understanding the low energy and low transverse momentum data.

Direct Photon Production

Measurements of the production of high-pT direct photons by a 515 GeV/c π- beam and 530 and 800 GeV/c proton beams in interactions with Be and H 2 targets are presented. The data span the kinematic ranges of 3.5 < pT < 12 GeV/c in transverse momentum and 1.5 units in rapidity. The inclusive direct-photon cross sections are compared with NLO pQCD calculations and expectations based on a phenomenological parton-kT model.
