Calculations of the Imaginary Part of Gauge Boson's Wave-function Renormalization Constants and the Modification of hep-ph/0301090

We have calculated the imaginary part of W and Z gauge boson’s wave-function renormalization constants (wrc.) in the complex-pole mass renormalization scheme and made atonement for the paper hep-ph/0301090 where the imaginary part of gauge boson’s wrc. has been ignored in the second renormalization scheme in section 4. But the conclusion of this section in hep-ph/0301090 doesn’t change.
