Add to ORKGCombining large N-C techniques and partial wave dispersion theory to analyze the pi pi scattering, without relying on any explicit resonance lagrangian, some interesting results are derived: (a) a general KSRF relation including the scalar meson contribution; (b) a new relation between resonance couplings, with which we have made an intensive analysis in several specific models; (c) low energy constants in chiral perturbation theory related with pi pi scattering in terms of the mass and decay width of resonances.Physics, AppliedCPCI-S(ISTP)
