Description

Systematic and careful studies are made on the properties of the IJ = 00 ππ and K K-bar coupled-channel system, using newly derived dispersion relations between the phase shifts and poles and cuts. The effects of nearby branch point singularities to the determination of the f0(980) resonance are estimated and discussed.
