LHC EW precision sub-group meeting

40-S2-A01 - Salle Anderson (CERN)

Show room on map

The focus of this meeting will be on the measurement of sin2thetaW, both on the theoretical side and on the experimental side (targeting a possible LHC combination in the future). There will also be other discussions following on from previous meetings (in particular concerning the measurement of mW) and more generally from existing and forthcoming precision measurements in the Drell-Yan sector.
