# Parton Distribution Functions

@article{Forte2022PartonDF, title={Parton Distribution Functions}, author={Stefano Forte and Joey Huston and Robert Samuel Thorne and Stefano Carrazza and Jun Gao and Zahari Kassabov and Pavel M. Nadolsky and Juan Rojo}, journal={Artificial Intelligence for High Energy Physics}, year={2022} }

We discuss the determination of the parton substructure of hadrons by casting it as a peculiar form of pattern recognition problem in which the pattern is a probability distribution, and we present the way this problem has been tackled and solved. Specifically, we review the NNPDF approach to PDF determination, which is based on the combination of a Monte Carlo approach with neural networks as basic underlying interpolators. We discuss the current NNPDF methodology, based on genetic…
