Abstract

The measurement of the W boson mass at LEP is discussed in detail and current preliminary results are presented. The results of the four LEP experiments using approximately 2.3 fb^–1 of data are combined to give m _W = 80.412±0.029(stat.)±0.031(sys.) GeV. This result is consistent with other direct measurements and with the value obtained from global fits to electroweak data.
