Scattering Theory: Time-Independent Methods

  • James Glimm
  • Arthur Jaffe


The S matrix is the central object of interest in field theory because it expresses the observed interactions between particles. The Chapter 13 definition of the S matrix does not provide a convenient framework for further analysis of its properties. However, we now show that the S matrix has a simple representation in terms of time-ordered correlation functions. This representation is convenient, and it allows, e.g., the construction of perturbation series, the decomposition into connected components, and the study of momentum space analyticity.
