The double fermionic contribution to the four-loop quark-to-gluon splitting function
We have computed the first 30 even-N moments for the double fermionic (nf2) part of the quark-to-gluon splitting function Pgq at the fourth order of perturbative QCD via the renormalization of off-shell operator matrix elements. From these results we have determined the all-N form, and hence the exa...
