<b>Finite-t Corrections to Hard Off-Forward Reactions </b><br>
<pre wrap="">We develop a general approach to the calculation of kinematic corrections ∼ t/Q<sup
class="moz-txt-sup">2</sup>, m<sup class="moz-txt-sup">2</sup>/Q<sup
class="moz-txt-sup">2</sup>
in hard processes which involve momentum transfer from the initial to the final hadron state.
As the principal result, the complete expression is derived for the time-ordered product of
two electromagnetic currents that includes all kinematic corrections to twist-four accuracy.
The results are immediately applicable, e.g. to the studies of deeply-virtual Compton scattering.</pre>
