We review basic ideas and recent developments on the determination of the parton substructure of the nucleon in view of applications to precision hadron collider physics. We review the way information on PDFs is extracted from the data exploiting QCD factorisation, and discuss the current main two approaches to parton determination (Hessian and Monte Carlo) and their use in conjunction with different kinds of parton parameterisation. We summarise the way different physical processes can be used to constrain different aspects of PDFs. We discuss the meaning, determination and use of parton uncertainties. We briefly summarise the current state of the art on PDFs for LHC physics.

Abstract
We review basic ideas and recent developments on the determination of the parton substructure of the nucleon in view of applications to precision hadron collider physics. We review the way information on PDFs is extracted from the data exploiting QCD factorisation, and discuss the current main two approaches to parton determination (Hessian and Monte Carlo) and their use in conjunction with different kinds of parton parameterisation. We summarise the way different physical processes can be used to constrain different aspects of PDFs. We discuss the meaning, determination and use of parton uncertainties. We briefly summarise the current state of the art on PDFs for LHC physics.Pubblicazioni consigliate
