Description
In recent years, precision in PDF determinations has significantly improved due to a combination of experimental (better statistics, control over uncertainties) and theoretical improvements (NNLO predictions, N3LO splitting functions). Thanks to this enhanced precision,
differences in the methodologies, data treatment and theory choices can now be resolved between different fitting collaborations. Differences which could have a phenomenological impact.
In this talk, I will discuss a systematic study carried out by the NNPDF collaboration on the data-theory agreement of a selection of observables from LHC Run II which are not yet included in PDF determinations.
In this quantitative study we present NNLO predictions for different PDF inputs and compare them to the latest data available.
