Abstract
The hadronic contribution to inelastic Compton scattering, M μν = ∫ dx e iq s ̇ x × 〈nω T ∗(J μ(x)J ν(0))ωm〉 , is computed to leading order in N −1 in two-dimensional QCD. Various kinematic limits are investigated. It is found that in the dual-Regge region of soft processes the photons interact as purely hadronic systems. Modification of dimensional counting rules is indicated by a study of a large-angle scattering analogue. In several hard inclusive non-light-cone processes, parton model ideas are confirmed. The impulse approximation is valid in a Bjorken-Paschos-like limit with very virtual photons. A Drell-Yan type annihilation mechanism is found in photoproduction of massive lepton pairs, leading to identification of a parton wave function for the photon.
