Parton Distributions with Theory Uncertainties: General Formalism and First Phenomenological Studies
The NNPDF Collaboration, Rabah Abdul Khalek, Richard D. Ball +11
We formulate a general approach to the inclusion of theoretical uncertainties, specifically those related to the missing higher order uncertainty (MHOU), in the determination of pa…

A First Determination of Parton Distributions with Theoretical Uncertainties
The NNPDF Collaboration, Rabah Abdul Khalek, Richard D. Ball +11
The parton distribution functions (PDFs) which characterize the structure of the proton are currently one of the dominant sources of uncertainty in the predictions for most process…

Nuclear Uncertainties in the Determination of Proton PDFs
Richard D. Ball, Emanuele R. Nocera, Rosalyn L. Pearson
We show how theoretical uncertainties due to nuclear effects may be incorporated into global fits of proton parton distribution functions (PDFs) that include deep-inelastic scatter…
