Magnetism on the stretched diamond lattice in lanthanide orthotantalates

Nicola D. Kelly, Lei Yuan, Rosalyn L. Pearson +3

The magnetic Ln ions in the fergusonite and scheelite crystal structures form a distorted or stretched diamond lattice which is predicted to host exotic magnetic ground stat…

An open-source machine learning framework for global analyses of parton distributions

Richard D. Ball, Stefano Carrazza, Juan Cruz-Martinez +14

We present the software framework underlying the NNPDF4.0 global determination of parton distribution functions (PDFs). The code is released under an open source licence and is acc…

The Path to Proton Structure at One-Percent Accuracy

Richard D. Ball, Stefano Carrazza, Juan Cruz-Martinez +14

We present a new set of parton distribution functions (PDFs) based on a fully global dataset and machine learning techniques: NNPDF4.0. We expand the NNPDF3.1 determination with 44…

Next generation proton PDFs with deuteron and nuclear uncertainties

Rosalyn L. Pearson, Richard D. Ball, Emanuele R. Nocera

As data become more precise, estimating theoretical uncertainties in global PDF determinations is likely to become increasingly necessary to obtain correspondingly precise PDFs. He…

Correlation of Theoretical Uncertainties in PDF Fits and Theoretical Uncertainties in Predictions

Richard D. Ball, Rosalyn L. Pearson

We show how to account for correlations between theoretical uncertainties incorporated in parton distribution function (PDF) fits, and the theoretical uncertainties in the predicti…

Deuteron Uncertainties in the Determination of Proton PDFs

Richard D. Ball, Emanuele R. Nocera, Rosalyn L. Pearson

We evaluate the uncertainties due to nuclear effects in global fits of proton parton distribution functions (PDFs) that utilise deep-inelastic scattering and Drell-Yan data on deut…
