Four-loop splitting functions in QCD – The gluon-to-quark case
We have computed the even-N moments N≤20 of the gluon-to-quark splitting function Pqg at the fourth order of perturbative QCD via the renormalization of off-shell operator matrix elements. Our results, derived analytically for a general gauge group, agree with all results obtained for this function...
