摘要：

We prove that the coefficient of the longitudinal part of the W-boson propagator close to resonance is equal to 1/(M(W)2 +iepsilon(L)), where epsilon(L) is proportional to squares of masses of those fermions that the W can decay to. Consequently, the full propagator has a non-g(munu) part that differs from the commonly used form, even in the limit of vanishingly small fermion masses.
