Description
Parton distribution functions (PDFs) are among the most important inputs for predictions at hadron colliders.
Today, state-of-the-art global analyses have reached the milestone of (approximated) N3LO accuracy. This represents an important step towards fully exploiting the data of the LHC, and the precision potential of future colliders.
I will discuss the main challenges, including missing perturbative information, the consistent tretament of theoretical and experimental uncertainties and the interplay between the different methodologies for PDF extraction and the accuracy of the result.
I will present benchmarks of results between different groups as well as the steps the community is taking towards robust N3LO PDF determinations.
