Mw topical meeting

23 Feb 2015, 14:00 → 24 Feb 2015, 19:00 Europe/Zurich

4/3-006 - TH Conference Room (CERN)

This meeting is dedicated to physics modeling issues in the Mw measurement at the LHC, and follows up on an initial meeting held in Firenze:

https://indico.cern.ch/event/340393/

We intend to discuss the following items:

• generator developments (higher-order corrections; polarization; reweighting...)
• developments in perturbative QCD and resummation
• PDF fits and uncertainties
• reports and questions from the experiments
