Abstract

Using the approach based on conformal symmetry we calculate the two-loop coefficient function for the vector flavor-nonsinglet contribution to deeply-virtual Compton scattering (DVCS). The analytic expression for the coefficient function in momentum fraction space is presented in the MS¯¯¯¯¯¯¯ scheme. The corresponding next-to-next-to-leading order correction to the Compton form factor ℋ for a ...
