Darren A. Tutek,Marsha M. Linehanal equations in terms of experimentally measurable (“renormalized”) quantities is still very arbitrary. E.g. sometimes only by abolishing the normal-ordering prescription “anomalies” become “normal” tadpole-contributions.灵敏 发表于 2025-3-26 04:41:33
Conference proceedings 1970efore the problems of renormalizability are all sorted out, but one may ten tatively state: 1) All matrix elements are finite for theories where the Dyson index D is less than two. 2) For the cases when D=2 or 3, counter-terms have been explicitly written which absorb all infinities and the theorie得意牛 发表于 2025-3-26 08:49:50
