Working Group on Electroweak precision measurements at the LHC

28 Nov 2011, 09:00 → 30 Nov 2011, 18:30 Europe/Zurich

TH Theory Conference Room (CERN)

Albert De Roeck (CERN), Michelangelo Mangano (CERN)

This meeting will update the status of EW LHC analyses and theoretical interpretations, and will initiate the discussion of the physics potential of the 2011 datasets. Given the relevance of EW measurements for PDF studies, we take the opportunity of this meeting to merge the discussion of both working groups into a single event. The regular PDF4LHC meeting will take place on Monday, and the PDF discussion related to EW physics will continue on Tuesday morning, in the first session of the EWWG.

Working group conveners:

• ATLAS: M. Boonekamp and J. Guimaraes da Costa
• CMS: M. Schmitt and G.De Monchenault
• LHCb: R. McNulty and T.Shears
• LPCC: M. Mangano
