Abstract
The total cross section for the process e+e−→W+W− followed by subsequent W-boson decays is calculated in the tree approximation by taking proper account of the W-boson width. It is found that the cross section is considerably modified by the finite-width effect in the threshold region, thus affecting the precise determination of the W-boson mass by experimental data. The effect of higher-order corrections is also considered.
