ON THE DEFINITION OF SCATTERING IN RELATIVISTIC QUANTUM FIELD THEORY,
Abstract
A relativistic interacting theory for neutral bosons and in which there can be no stable bound states is studied. The theory is obtained by embedding twoparticle relativistic quantum mechanics in quantum field theory by means of a procedure recently given by Sudarshan. This results in a theory in which there is scattering in the two-partical channel only. An 'interacting' field operator psi(x) is defined for the theory. It is then found that under the usual formulation of axiomatic quantum field theory psi(x) must be regarded as a 'local free-field operator'. However, there is inherent in psi(x) scattering information. A new asymptotic condition for field operators is then proposed, whereby this scattering information may be extracted. A heuristic discussion of the physical significance of the asymptotic condition is also given. (Author)
