Collinear splitting, parton evolution and the strange-quark asymmetry of the nucleon in NNLO QCD
German Rodrigo, Stefano Catani, Daniel de Florian +1
We consider the collinear limit of QCD amplitudes at one-loop order, and their factorization properties directly in colour space. These results apply to the multiple collinear limi…
Perturbative generation of a strange-quark asymmetry in the nucleon
Stefano Catani, Daniel de Florian, German Rodrigo +1
We point out that perturbative evolution in QCD at three loops generates a strange-antistrange asymmetry s(x)-sbar(x) in the nucleon's sea just from the fact that the nucleon has n…
The radiative return at phi- and B-factories: FSR for muon pair production at next-to-leading order
Henryk Czyz, Agnieszka Grzelinska, Johann H. Kuhn +1
Muon pair production through the radiative return is of importance for a measurement of the hadronic production cross section in two ways: it provides an independent calibration an…
