The Study of the W Boson

Abstract The status of the measurement of the W boson mass at LEP2 is reviewed. Properties of the W such as branching ratios into quarks and leptons and couplings to other neutral gauge bosons are reported. Four-fermion production cross sections in e + e − collisions are also presented. To cite this article: O. Buchmuller et al., C. R. Physique 3 (2002) 1173–1181.
