Abstract

Parton distribution functions are important quantities describing the probability densities of quarks and gluons within e.g. the proton. They have been parameterized and fitted phenomenologically to known experimental data, and serve as key inputs to predicting, with estimated uncertainties, cross sections in high-energy scattering experiments. A precision first-principle calculation of PDFs from quantum chromodynamics (QCD), the underlying theory of strong interactions, has long been a holy grail in nuclear and high-energy physics. I will review the recent developments in this direction. Download:
