Description

This meeting will serve as a follow-up on the November workshop on the three main topics discussed, namely PDF impact on precision EW measurements, pTW/Z resummation predictions, and QED/EW corrections to Z DY observables. It will also serve as a preparation for the PDF4LHC forum discussion on the following afternoon and for the general LPCC SM meeting which will take place on 13-14th of December.
