Electroweak Physics at LHC

Abstract

The Large Hadron Collider, LHC, though meant for discovery, will provide enough data from early phase to also perform various studies of Standard Model processes in as yet unexplored kinematic regions. Precision measurements of the electroweak variables will be possible due to the large rates of W and Z boson productions combined with clean leptonic signatures. Examples of simulation results from CMS and ATLAS collaboration studies are presented to show the wide variety of measurements possible and how various issues like background estimation, determination of systematic effects will be taken care of by the experiments.Comment: Invited talk at the Hadron Collider Physics Symposium (HCP2008), Galena, Illinois, USA, May 27-31, 2008; 10 pages, 8 pdf figures, pdflate
