Description

An important aim of the LHC is the precise measurement of W and Z boson production cross sections, as these may be used to extract fundamental electroweak parameters as well as further test and constrain existing QCD models. In first data they may also be used as 'standard candle events' to understand detector performance. Any significant deviation from the predicted behaviour of these events could be one of the first indications of physics beyond the Standard Model, and so understanding these events is of paramount importance to new physics searches. It is important to make a data driven measurement of the cross sections and, whenever possible, not to rely on Monte Carlo simulation. Such a method of determining these cross sections in the ATLAS detector is outlined for the electron channel, with particular focus given to recent studies into a data driven determination of MET resolution and measurement of trigger efficiency.
