Global analyses of PDFs in the precision era
Abstract
Parton distribution functions or PDFs are determined through global fits to an ever-increasing array of data, including deep-inelastic scattering at fixed-target experiments and HERA, and hadron collisions at the Tevatron and LHC. As the dataset has expanded, theoretical accuracy has improved from partial next-to-next-to-leading order (NNLO) coverage about 20 years ago to approximate N3LO global fits today. The fitting collaborations must reconcile these complex calculations and data analyses while ensuring that quoted PDF uncertainty bands remain reliable.

As the dataset has expanded, theoretical accuracy has improved from partial next-to-next-to-leading order (NNLO) coverage about 20 years ago to approximate N^3LO global fits today. The fitting collaborations must reconcile these complex calculations and data analyses while ensuring that quoted PDF uncertainty bands remain reliable.
