Abstract
The mass, m W, and the total decay width, ΓW, are fundamental properties of the Wboson. Together with other electroweak parameters such as the Z-boson mass and the weak mixing angle the precise determination of mW provides a stringent test of the Standard Model at the level of quantum corrections. In addition to the measurement of the Z mass and the weak mixing angle performed at LEP 1 and SLC a precise measurement of the W mass is mandatory for this test. The precision of the direct measurement of the W mass has to compete with the 23 MeV accuracy on mW when it is derived indirectly from the electroweak precision data acquired on the Z resonance.
