Abstract

In last ten years many authors have attempted to formulate a consistent relativistic quantum field theory with unstable particles [1]. At present one can state only that the role of unstable particles was clarified in some soluble models: the lowest Lee model sectors [2], Zachariasen model [3]. The main difficulties in the construction of general relativistic theory with unstable particles appeared to be
  1. 1.

    to incorporate correctly the instability property into the theory,

     
  2. 2.

    to get the consistency with an experimental fact that in asymptotic space — time regions there are only observed free stable particles.

     

The aim of this lecture is to discuss the applicability to the description of strongly unstable objects the field operator ϕ(x;s), with continuous spectrum of asymptotic masses.

    The unstable particles were mainly studied in the framework of Ŝ-matrix theory, where the Peierl’s concept of complex pole on second Rieman sheet of the propagator has been used. Below we list some papers, from “classical” period 1958 — 1963, where there were made many attempts to find the place of unstable particles in general framework of relativistic local QFT: a) P. T.
