The Path to NLO Parton Distributions
The NNPDF Collaboration, Richard D. Ball, Andrea Barontini +16
We extend the existing leading (LO), next-to-leading (NLO), and next-to-next-to-leading order (NNLO) NNPDF4.0 sets of parton distribution functions (PDFs) to approximate next-to-ne…

Determination of the theory uncertainties from missing higher orders on NNLO parton distributions with percent accuracy
The NNPDF Collaboration, Richard D. Ball, Andrea Barontini +16
We include uncertainties due to missing higher order corrections to QCD computations (MHOU) used in the determination of parton distributions (PDFs) in the recent NNPDF4.0 set of P…

Photons in the proton: implications for the LHC
The NNPDF Collaboration, Richard D. Ball, Andrea Barontini +16
We construct a set of parton distribution functions (PDFs), based on the recent NNPDF4.0 PDF set, that also include a photon PDF. The photon PDF is constructed using the LuxQED for…
