DESCRIPTION:Parton distribution functions (PDFs) are non-perturbative obje
 cts in QCD which are central to any theory prediction. Modern global analy
 ses of the PDF include collider measurements which probe energies well abo
 ve the electroweak scale. While these provide powerful constraints on the 
 PDFs\, they are also sensitive to beyond the standard model (BSM) dynamics
  if these affect the fitted distributions. I will present a first simultan
 eous determination of the PDFs and BSM effects from deep-inelastic structu
 re function data by means of the NNPDF framework. Our results demonstrate 
 how BSM effects that might otherwise be reabsorbed into the PDFs can be sy
 stematically disentangled.
