We carry out the first complete calculation of kinematic power corrections ∼t/Q2 and ∼m2/Q2 to the helicity amplitudes of deeply virtual Compton scattering. This result removes an important source of uncertainties in the quantum chromodynamics predictions for intermediate momentum transfers Q2∼1–10 …
