Wave-function renormalization prescriptions
Yong Zhou · arXiv (Cornell University) · 2005
We introduce two set Wave-function Renormalization Constants (WRC) and find the hermitian conjugation relationship between them is broken by the singularities of Feynman amplitudes. By introducing the antiparticle's WRC and the CPT conservation law we obtain a new wave-function renormalization condition which is used to completely determine the WRC.
