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.
