LHC EW precision sub-group meeting

Wednesday 25 Apr 2018, 09:00 → 19:25 Europe/Zurich

40/S2-A01 - Salle Anderson (CERN)

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.

10:00 → 10:10 Introduction

Speaker: Daniel Froidevaux (CERN)
