Abstract

Using the recent results on the contributions of descendants of the leading twist operators to the operator product expansion of two electromagnetic currents we derive explicit expressions for the kinematic finite-t and target mass corrections to the DVCS helicity amplitudes to the 1/Q(4) power accuracy. The cancellation of IR divergences for kinematic corrections is demonstrated to all powers in ...
