Description
Pair production of W bosons near threshold is important
for a precise measurement of the W boson mass. Accurate theoretical
predictions for e^+ e^- -> four fermions require a systematic treatment
of finite-width effects. In this talk I discuss unstable particle
effective field theory and perform a dedicated study of the
accuracy of the W mass on the basis of a NLO calculation.
