On the Absence of the Zeno Effect in Relativistic Quantum Field Theory
R. F. Alvarez-Estrada, J. L. Sanchez-Gomez
Abstract
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.
