000617343 520__ $$aMaking use of conformal symmetry of large-n f QCD in d = 4 − 2ϵ dimensions atthe Wilson-Fischer fixed point, we calculate the two-loop coefficient function in the operatorproduct expansion of two electromagnetic currents in a general kinematics with two differentphoton virtualities. This result is necessary for the description of the double deeply virtualCompton scattering to the next-to-next-to-leading order accuracy, but is also interesting fora range of other two-photon processes. We present analytic expression for the coefficientfunction in momentum fraction space in the MS scheme and study its numerical impacton the Compton form factors for a simple model of the generalized parton distribution. Thecalculated corrections turn out to be large and are significant in the kinematics of the proposedexperiments.
