S-wave pi pi scattering and the S poles
The I=0 S-wave pi pi scattering amplitude is analysed with a primary interest in the S/sup */. The amplitude corresponding to the S/sup */ is parametrized in terms of pole positions. The recent CERN-Munich energy-independent partial-wave solution is reproduced better by an amplitude with two poles (...
