The present theoretical knowledge about photons and hard photoproduction processes, i.e. the production of jets, light and heavy hadrons, quarkonia, and prompt photons in photon-photon and photon-hadron collisions, is reviewed. Virtual and polarized photons and prompt photon production in hadron collisions are also discussed. The most important leading and next-to-leading order QCD results are compiled in analytic form. A large variety of numerical predictions is compared to data from TRISTAN, LEP, and HERA and extended to future electron and muon colliders. The sources of all relevant results are collected in a rich bibliography.Comment: Habilitationsschrift, scheduled for publication in Rev. Mod. Phys., 126 pages, 61 figure

We find that an equation of state for hot hadronic matter consisting of all baryons having M < 2 GeV and all mesons having M < 1.5 GeV, along with Hagedorn resonances in thermal and chemical equilibrium, matches rather smoothly with lattice equation of state (p4 action, N τ = 8) for T up to ≈ 200 MeV, when corrected for the finite volume of hadrons.Next we construct two equations of state for strongly interacting matter; one, HHL, in which the above is matched to the lattice equation of state at T = 165 MeV and the other, HHB, where we match it to a bag model equation of state with critical temperature T c = 165 MeV. We compare particle spectra, thermal photon spectra and histories of evolution of the quark-gluon plasma produced in the central collision of gold (lead) nuclei at RHIC (LHC) energies, considering ideal hydrodynamical expansion of the system. The particle and thermal photon spectra are seen to differ only marginally, for the two equations of state. The history of evolution shows differences in the evolution of temperature and radial velocity, as one might expect.We calculate intensity interferometry of thermal photons and find it to be quite distinct for the two equations of state, especially for the outward correlation. The longitudinal correlation also shows a dependence on the equation of state, though, to a smaller extent.

“…Similar discrepancies have been observed between PQCD calculations and other measurements of high-p T direct-photon and 0 production [50 -52] and are attributed to the effect of initialstate soft-gluon radiation (see also Refs. [53][54][55]). The importance of including gluon emission through the resummation formalism has long been recognized, and the corresponding calculations have been available for some time for the diphoton process [56,57].…”

Measurements of the production of high transverse momentum direct photons by a 515 GeV=c ÿ beam and 530 and 800 GeV=c proton beams in interactions with beryllium and hydrogen targets are presented. The data span the kinematic ranges of 3:5 < p T < 12 GeV=c in transverse momentum and 1.5 units in rapidity. The inclusive direct-photon cross sections are compared with next-to-leading-order perturbative QCD calculations and expectations based on a phenomenological parton-k T model.
