Abstract

We present a detailed benchmarking of different treatments of the QCD evolution of unpolarized PDFs at approximate N³LO (aN³LO) order in the QCD coupling. Namely, the implementations in the public aN³LO releases of the MSHT and NNPDF global PDF fitters, as well as that of the theoretical FHMRUVV collaboration are compared. This follows the same procedure as in previous benchmarking exercises at lower order, that is by considering the impact of this evolution on a set of simple toy PDFs.
