Diffractive di-hadron production at NLO within the shockwave formalism
Abstract
We compute the next-leading-order cross-sections for diffractive electro- or photoproduction of a pair of hadrons with large pT, out of a nucleus or a nucleon. A hybrid factorization is used, mixing collinear and small-x factorizations, more precisely shockwave formalism. We demonstrate the cancellation of divergences and extract the finite parts of the differential cross-section in general kinematics.
