DESCRIPTION:A robust and detailed knowledge of the proton subn
 uclear structure is a crucial input at the Large H
 adron Collider (LHC). The uncertainty on the Parto
 n Distribution Functions (PDFs) - the functions th
 at parametrise protons in terms of their elementar
 y constituents\, quarks and gluons - often represe
 nts a limiting factor in the accuracy of theoretic
 al predictions at hadron colliders. At the same ti
 me the precise measurements taken at the LHC give 
 a powerful insight on the proton. I will give an o
 verview of the theoretical aspects behind PDFs det
 ermination and on the state of the art of modern P
 DFs fits. I will then mention the new exciting cha
 llenges that the precision frontier is presenting\
 , such as the interplay between the proton structu
 re and the hunt for new physics beyond the Standar
 d Model.
