Complete N f 2 $$ {N}_f^2 $$ contributions to four-loop pure-singlet splitting functions
Abstract The scale evolution of parton distributions is determined by universal splitting functions. As a milestone towards the computation of these functions to four-loop order in QCD, we compute all contributions to the pure-singlet quark-quark splitting functions that involve two closed fermion l...
