| Title | Evolution of Parton Distribution Functions in the Short-Distance Factorization Scheme | ||||
| Abstract | Lattice QCD offers the possibility of computing parton distributions from first principles, although not in the usual M S factorization scheme. We study in this paper the evolution of non-singlet parton distribution functions (PDFs) in the short-distance factoriza- tion scheme which notably arises in lattice calculations in the pseudo-distribution approach. We provide an assessment of non-perturbative evolution of PDFs from already published lat- tice matrix elements, and show how this evolution can be used to reduce the fluctuation of the lattice data. We compare our result with expectations obtained thanks to a perturbative matching to MSbar. By highlighting the limitations of the current computations, we advocate for a new strategy using lattice calculations in small volume | ||||
