On the status of the 4-loop splitting functions in QCD
S. Moch, A. Vogt
We briefly discuss recent results on the four-loop splitting functions for the scale dependence of the parton distributions of hadrons. The three non-singlet cases are now complete…

We present the first results for the next-to-next-to leading order (NNLO) corrections to the semi-inclusive deep-inelastic scattering process in perturbative quantum chromodynamics…

S. Moch, B. Ruijl, T. Ueda +2
We have extended our previous computations of the even-N moments of the flavour-singlet four-loop splitting functions to N = 12 for the pure-singlet quark case and N = 10 for all o…

We evaluate the impact of recent SeaQuest (E906 experiment) data on dimuon production in proton-deuteron and proton-proton collisions on parton distribution functions (PDFs). We fi…

J. Fiaschi, F. Giuli, F. Hautmann +2
We study the influence of theoretical systematic uncertainties due to the quark density on LHC experimental searches for -bosons. Using an approach originally proposed in…
