A robust and detailed knowledge of the proton subnuclear structure is a crucial input at the Large Hadron Collider (LHC). The uncertainty on the Parton Distribution Functions (PDFs) – the functions that parametrise protons in terms of their elementary constituents, quarks and gluons – often represents a limiting factor in the accuracy of theoretical predictions at hadron colliders. At the same time the precise measurements taken at the LHC give a powerful insight on the proton. I will give an overview of the theoretical aspects behind PDFs determination and on the state of the art of modern PDFs fits. I will then mention the new exciting challenges that the precision frontier is presenting, such as the interplay between the proton structure and the hunt for new physics beyond the Standard Model.
