Measurement of the W mass at LEP and recent Results of the Electroweak Fit
Christian Rosenbleck
Abstract
The measurement of the mass of the W boson, mW, by direct reconstruction is described. The combination of all measurements of the four LEP experiments yields mW = 80.412 +- 0.042 GeV. Together with several other measurements the extracted mW value enters the electroweak fit, which tests the Standard Model (SM) predictions and extracts SM parameters which have not yet been measured. The latest results of the fit are presented.
