We describe a systematic approach (Braun and Manashov (2011) [24]) to the calculation of kinematic corrections alpha t/Q(2), m(2)/Q(2) in hard exclusive processes which involve momentum transfer from the initial to the final hadron state. As an example, the complete expression is derived for the time-ordered product of two electromagnetic currents that includes all kinematic corrections due to the quark distribution to twist-four accuracy. The results are applicable e.g. to the studies of deeply-virtual Compton scattering. (C) 2011 Elsevier B.V. All rights reserved.
