We review the recent developments of virtual Compton scattering. We focus on the kinematical regimes which look the most promising. The threshold regime gives access to the generalized polarizabilities of the proton. The hard scattering regime allows tests of perturbative QCD predictions and of the valence quark wave function. The Bjorken regime is closely related to deep inelastic scattering. It gives access to the off-forward parton distributions which generalize the ordinary parton distributions and may shed a new light on the spin problem. For each regime we discuss the experimental perspectives and the role of the Bethe-Heitler background.

“…[13], the third version of the CTEQ collaboration model [15], because it is characterized by a particularly suitable extrapolation at very low Bjorkenx. The evolution in Q 2 is realized by next-to-leading order Altarelli-Parisi equations from initial Q 2 0 = 2.56 GeV 2 .…”

“…In hadronic collisions, both with fixed targets [10] and colliders [11,12], prompt photon processes provide a means to study the gluon content of the proton [13,14]. Fixed target studies [15] have also provided a first confirmation of prompt photon processes in photoproduction, at a level consistent with QCD expectations.…”

Events containing an isolated prompt photon with high transverse energy, together with a balancing jet, have been observed for the first time in photoproduction at HERA. The data were taken with the ZEUS detector, in a γp centre of mass energy range 120-250 GeV. The fraction of the incoming photon energy participating in the production of the prompt photon and the jet, x γ , shows a strong peak near unity, consistent with LO QCD Monte Carlo predictions. In the transverse energy and pseudorapidity range 5 ≤ E γ T < 10 GeV, −0.7 ≤ η γ < 0.8, E jet T ≥ 5 GeV, and −1.5 ≤ η jet ≤ 1.8, with x OBS γ > 0.8, the measured cross section is 15.3±3.8±1.8 pb, in good agreement with a recent NLO calculation.
