Deeply virtual electroproduction of photons and mesons on the nucleon: Leading order amplitudes and power corrections
We estimate the leading order amplitudes for exclusive photon and meson electroproduction reactions at large ${Q}^{2}$ in the valence region in terms of skewed quark distributions. As experimental investigations can currently only be envisaged at moderate values of ${Q}^{2},$ we estimate power corrections due to the intrinsic transverse momentum of …
