394“…One of the most satisfactory aspects of relativistic local quantum field theory is the asymptotic theory of Haag and Ruelle: starting from a few simple hypotheses (locality, relativistic invariance, and spectrum, including the explicit exclusion of zero-mass states) the existence of the scattering operator S and of scattering amplitudes is established: these amplitudes can then be expressed through the 'reduction formulae' of L.S.Z. …”

395“…The authors examine the possibility of constructing a quantum field theory of the scattering of a system of hadrons, which lie on Regge trajectories, by associating the spectrum with a mass operator involving an internal co-ordinate. …”
