Measurement of the W mass at LEP and recent Results of the Electroweak Fit
The measurement of the mass of the W boson, m_W, by direct reconstruction is described. The combination of all measurements of the four LEP experiments yields m_W = 80.412 +- 0.042 GeV. Together with several other measurements the extracted m_W value enters the electroweak fit, which tests the Stand...

| Sumario: | The measurement of the mass of the W boson, m_W, by direct reconstruction is described. The combination of all measurements of the four LEP experiments yields m_W = 80.412 +- 0.042 GeV. Together with several other measurements the extracted m_W 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. |
