Measurement of the W mass at LEP and recent Results of the Electroweak Fit
Christian Rosenbleck
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…

Determination of the LEP Beam Energy using Z Recoil Events
Christian Rosenbleck
The precise knowledge of the beam energy, E_beam, at the LEP collider is important to reduce the systematic uncertainty on the W mass. The measurements by the LEP energy group can…
