Abstract We give a complete representation of virtual Compton scattering γ ∗ p→γp at large initial photon virtuality Q 2 and small momentum transfer squared t in terms of the light-cone wavefunctions of the target proton. We verify the identities between the skewed parton distributions H(x,ζ,t) and E(x,ζ,t) which appear in deeply virtual Compton scattering and the corresponding integrands of the Dirac and Pauli form factors F 1 (t) and F 2 (t) and the gravitational form factors A q (t) and B q (t) for each quark and anti-quark constituent. We illustrate the general formalism for the case of deeply virtual Compton scattering on the quantum fluctuations of a fermion in quantum electrodynamics at one loop.
