摘要: High-energy factorization in QCD is investigated beyond leadinng order and its relationship to the theorem of mass singularities established any collinear accuracy. Flavour non-singlet observables are shown be regular at small x by perturbation theory. In singlet sector, we derive relevant master equations for space-like evolution gluons quarks. Their solution enables us sum next-to-leading corrections small-x behaviour quark anomalous dimensions deep inelastic scattering coefficient functions. We present results both MS DIS schemes.
