Description
Parton distribution functions (PDFs) are of supreme importance in modern high energy physics. Firstly, they encode fundamental information on the structure of hadrons as probed in high energy reactions. Moreover, PDFs are an indispensable tool for the computation of cross sections at hadron colliders such as the LHC providing the link between the perturbatively calculable parton level cross sections for quark and gluon scattering processes and the observable cross sections in hadron-hadron collisions. In this talk, I will give a basic introduction to PDFs in nucleons and nuclei and describe how they are determined in so-called global analyses of a large variety of different scattering processes.
