Soft-collinear resummation in deeply virtual Compton scattering
Abstract
We derive an all order resummation formula for the deeply virtual Compton scattering (DVCS) amplitude, which takes into account soft gluon exchanges in the non-singlet quark coefficient function. We identify the ladder diagrams responsible in light-like gauge for [alphaS log2 (x +/- xi)]n contributions. The resummed series results in a simple closed expression.
