Quark beam function at next-to-next-to-next-to-leading order in perturbative QCD in the generalized large- Nc approximation
We present the matching coefficient for the quark beam function at next-to-next-to-next-to-leading order in perturbative QCD in the generalized large Nc-approximation, Nc ∼ Nf ≫ 1. Although several refinements are still needed to make this result interesting for phenomenological applications, our co...
