Description
We present our ongoing calculation of the next-to-leading order evolution equations for Generalized Parton Distributions (GPDs) in the flavour-non-singlet sector. We discuss the advantages and challenges associated with the use of the lightcone gauge. We show how the calculation can be automated using a set of analytically computable master integrals. The (spurious) rapidity divergences appear at the intermediate stage due to gluon propagators in the lightcone gauge. We explicitly prove their cancellation between different diagrams providing a strong consistency check.
