The Inner Nature of the Proton

Protons are ubiquitous in nature as they can be found in allnuclei. According to our current knowledge of the

fundamental laws of nature, the proton is described as a compositeparticle made of quarks that are confined by strong interactions.

Interestingly protons are also our tool of choice to investigate physicsbeyond the Standard Model. The Large Hadron Collider at CERN exploresthe smallest distances ever probed by colliding protons at very highenergies. Understanding the structure of the proton is a key element inorder to be able to exploit the results from the experiments.

In this talk I will review the foundations of thetheoretical description of the proton structure interms of Parton Distribution Functions, discussthe possible ways to determine them, andpresent a selection of the latest results in thisfield.
