Conformal moments of the two-loop coefficient functions in DVCS (2512.14295v1)
Published 16 Dec 2025 in hep-ph
Abstract: We develop a new technique and calculate conformal (Gegenbauer) moments of the two-loop coefficient functions in Deeply Virtual Compton Scattering (DVCS). These results are necessary for the extraction of the generalized parton distributions from the experimental data to the NNLO accuracy within the Mellin-Barnes approach.
