Description

The meeting will be at CERN from Tuesday 13th of November morning to Thursday 15th of November late afternoon. The whole day Tuesday will be devoted to a discussion of PDF issues related to precision EW measurements at the LHC in preparation for a discussion within the PDF4LHC forum on December 13th. The rest of the workshop will be devoted as usual to theoretical QCD and QED/EW issues and to recent experimental progress.
