| 英文摘要 | In order to obtain proper wavefunction renormalization constants for unstable fermions and be consistent with Breit-Wigner formula in the resonant region, we have assumed an extension of the LSZ reduction formula for unstable fermions and adopted an on-shell mass renormalization scheme in the framework without field renormalization. The comparison of the gauge dependence of physical amplitude between on-shell mass renormalization and complex-pole mass renormalization has been discussed. After obtaining the fermion wavefunction renormalization constants, we extend them to two matrices in order to include the contributions of off-diagonal two-point diagrams at fermion external legs for the convenience of calculations of S-matrix elements. |
