| description | Recently a new set of Parton Distribution Functions (NNPDF1.2) has been produced and released by the NNPDF Collaboration. The inclusion of dimuon data in the analysis allows a determination of the strange content of the proton with faithful uncertainty estimation together with a precision determination of electroweak parameters. In this contribution, we discuss some of the implications of the NNPDF1.2 set, and in particular of its uncertainty determination of the strange PDFs, for LHC phenomenology. First of all, we study the impact on the electroweak boson production cross-section, with special attention to the σ(Z)/σ(W) ratio. Then we revisit the tt production cross-section, and perform a comparison of partonic fluxes between various PDF sets. Finally, we discuss the potential of using associated production of W with a charm quark at the Tevatron and the LHC to constrain the proton strangeness. |
