Can $\overline{MS}$ parton distributions be negative?

High Energy Physics - Phenomenology 2021-08-25 v1

Abstract

We review our recent paper, where we proved Parton distributions functions (PDFs) to be positive at NLO in the MS\overline{MS} factorization scheme. We present some additional material that was useful in completing the steps for the actual proof, but we won't attempt to report on the full proof, but referring the reader to the paper itself.
