Response to "Parton distributions need representative sampling"
The NNPDF Collaboration, Richard D. Ball, Juan Cruz-Martinez +7
We respond to the criticism raised by Courtoy et al., in which the faithfulness of the NNPDF4.0 sampling is questioned and an under-estimate of the NNPDF4.0 PDF uncertainties is im…
Parton distributions with scale uncertainties: a MonteCarlo sampling approach
Zahari Kassabov, Maria Ubiali, Cameron Voisey
We present the MCscales approach for incorporating scale uncertainties in parton distribution functions (PDFs). The new methodology builds on the Monte Carlo sampling for propagati…
Regularising experimental correlations in LHC data: theory and application to a global analysis of parton distributions
Zahari Kassabov, Emanuele R. Nocera, Michael Wilson
We show how an inaccurate determination of experimental uncertainty correlations in high-precision LHC measurements may undermine the reliability of the associated . We formul…
