Abstract

Describing many applications in hadronic physics beyond certain kinematic regions where the factorization approximations no longer apply remains a challenge for quantum chromodynamics (QCD). Using a simplified, QCD-like theoretical model, the authors show that the boundaries of regions of applicability of QCD factorization methods may be pushed further.
