Next-to-Leading Corrections at Small X
S. Catani, F. Hautmann
We discuss the role of sub-leading corrections to deep inelastic processes in the small-x regime, and report recent results on the calculation of coefficient functions and quark an…
Surprises from Quarkonium Decay into Photons
S. Catani, F. Hautmann
The perturbative QCD approach to quarkonium decay into a photon and hadrons is reconsidered. It is shown that a consistent treatment within perturbative QCD calls for the introduct…
Next-to-Leading Corrections at Small X from Quark Evolution
F. Hautmann
Deep inelastic processes at small x are discussed in the framework of perturbative QCD at high energy. New results are presented on the quark anomalous dimensions beyond the leadin…
High-Energy Factorization and Small-X Deep Inelastic Scattering Beyond Leading Order
S. Catani, F. Hautmann
High-energy factorization in QCD is investigated beyond leading order and its relationship to the factorization theorem of mass singularities is established to any collinear accura…
