We calculate the amplitude for the forward electroproduction of two light vector mesons in next-to-leading order BFKL. This amplitude represents the first next-to-leading order amplitude ever calculated for a collision process between strongly interacting colorless particles.

We consider threshold pion electroproduction on a proton target for photon virtualities in the region 1 − 10 GeV. The S-wave multipoles at threshold, E0+ and L0+, are calculated using light-cone sum rules.

We review the results of our studies on the charge and the spin asymmetries in the electroproduction of π + π − which are the observables sensitive to the Pomeron-Odderon interference.

We consider the reactions γ p → M B, with M B being either K + Λ, K + Σ 0 , or π + n, within a diquark model which is based on perturbative QCD. The model parameters and the quark-diquark distribution amplitudes of the baryons are taken from previous investigations of electromagnetic baryon form factors and Compton-scattering off protons. Reasonable agreement with the few existing photoproduc-t...
