Abstract:
On the basis of the model of a four-particle direct interaction without derivative coupling, relations are obtained between the various renormalized quantities related to pion-pion interaction. By considering only two-pion intermediate states but preserving crossing symmetry and unitarity up to the production threshold, closed systems of non-linear integral equations are obtained from these relations to describe approximately the low-energy pion-pion scattering.
