โœฆ Synopsis

Deeply virtual Compton scattering (DVCS) and the exclusive electroproduction of vector mesons (p0, p:L, ~, ยข) and pseudoscalar mesons (rr ยฐ, 7r ยฑ, ...) in the Bjorken regime are sensitive to the recently introduced off-forward parton distributions. We calculate the leading order amplitudes for DVCS and hard meson electroproduction reactions in the valence region and use a model ansatz for the OFPD's to give estimates of observables relevant for experiments at COMPASS, HERMES and JLAB.

We present a non-perturbative QCD calculation of high-energy diffractive photo-and leptoproduction of vector mesons p, p' and p" on a nucleon. The initial photon splits up in a qq-dipole and transforms into a vector meson by scattering on the quark-diquark nucleon. The dipole-dipole scattering ampl
