关于相对论量子场论中Zeno效应的缺失

On the Absence of the Zeno Effect in Relativistic Quantum Field Theory

R. F. Alvarez-Estrada, J. L. Sanchez-Gomez

摘要:

研究了相对论量子场论可重整化模型中衰变粒子的时间演化。后者和非相对论量子力学之间的显着差异被发现-特别是,芝诺效应似乎是在这样的RQFT模型缺席。传统的重整化在某些情况下产生有限时间行为,但在其他情况下无法产生有限的生存概率。

英文摘要:

We study the time evolution of decaying particles in renormalizable models of Relativistic Quantum Field Theory. Significant differences between the latter and Non Relativistic Quantum Mechanics are found -in particular, the Zeno effect seems to be absent in such RQFT models. Conventional renormalization yields finite time behavior in some cases but fails to produce finite survival probabilities in others.
