The new methodology builds on the Monte Carlo sampling for propagating experimental uncertainties into the PDF space that underlies the NNPDF approach, but it extends it to the space of factorisation and renomalisation scales. A prior probability is assigned to each scale combinations set in the theoretical predictions used to obtain each PDF replica in the Monte…</p><p><a href="https://hackerpaper.kaipfister.de/p/2207.07616/">Paper and discussion history</a>.
