How suppressed are the radiative interference effects in heavy unstable particle production?

Abstract

We present a \lq\lq theorem" which quantifies, for inclusive processes, the level of suppression of the radiative interference effects between the production and decay stages of heavy {\it unstable} particles. The theorem, which is based on very general physical arguments, is applicable to all orders in the coupling.
