New frontiers in the determination of the proton structure



The parametrization of the proton's structure via the determination of Parton Distribution Functions (PDFs) is a crucial theoretical input at the LHC. The PDF uncertainty is often a limiting factor in the accuracy of theoretical predictions. At the same time the LHC is delivering a number of precise measurements that provide precious information on the proton's structure.  In this seminar, I will give a broad overview on the theory behind and on the state-of-the-art of PDF determinations. I will then mention the new challenges that modern fits of PDFs face, due to the unprecedented precision of the LHC data.
