چکیده
We compute amplitude of deeply virtual Compton scattering in the parton model. We found that the amplitude in the hard regime up to the accuracy O(1/Q) depends on new skewed parton distributions (SPD's). These additional contributions make the DVCS amplitude explicitly transverse. The new SPD's contribute to various spin, charge and azimuthal asymmetries at the same order in 1/Q as the leading twist SPD's H, H, E and E.
