Title: The NNPDF approach to parton determination: ideas and results
Abstract:
I discuss the importance of parton distributions (PDFs) for physics at the LHC.
After reviewing the current state of the art of PDF knowledge, I present the novel approach to PDF determination which has been pursued by the NNPDF collaboration. I show how the NNPDF methodology, based on a monte carlo approach combined with the use of neural network, addresses the delicate issue of accurate determination of PDF uncertainties. I present recent NNPDF PDF sets, compare them with other available sets, and argue that they are most suited for discovery physics.
