Three-loop results and soft-gluon effects in DIS
arXiv:hep-ph/0309056
Abstract
We have calculated the fermionic contributions to the flavour non-singlet structure functions in deep-inelastic scattering (DIS) at third order of massless perturbative QCD. We discuss their implications for the threshold resummation at the next-to-next-to-leading logarithmic accuracy.
