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.
