Description
We prove that the coefficient of the longitudinal part of the W-boson propagator close to resonance is equal to 1/(MW2+iεL), where εL is proportional to squares of masses of those fermions that the W can decay to. Consequently, the full propagator has a non-gμν part that differs from the commonly used form, even in the limit of vanishingly small fermion masses
