摘要：

Pie study the time evolution of decaying particles in renormalizable models of relativistic quantum field theory (RQFT). Significant differences between the latter and nonrelativistic quantum mechanics are found - in particular, the Zeno effect seems to be absent in such RQFT models. Conventional renormalization yields finite time behaviour in some cases but fails to produce finite survival probabilities in others. (C) 1999 Elsevier Science B.V.
