Implementing Unitarity in Perturbation Theory
Abstract
Perturbative unitarity can be implemented and exact unitarity can be restored in perturbation theory by suitable parametrizations. The basic ideas for such parametrizations are discussed, and simple examples to illustrate the formalism are given.
