NLO collinear factorization of large mass diphoton photoproduction amplitude
Published 29 Jul 2021 in hep-ph, hep-ex, and nucl-ex | (2107.14108v1)
Abstract: We calculate large mass diphoton exclusive photoproduction in the framework of collinear QCD factorization at next to leading order in {\alpha}s and at leading twist. Collinear divergences of the coefficient function are absorbed by the evolution of the generalized parton distributions (GPDs). This result enlarges the existing factorization proofs to 2 -> 3 processes, opening new reactions to a trustable extraction of GPDs.
