Rigorous Bounds on Strong Interaction Coupling Constants
… they impose absolute limits on the size of the renormalized coupling constant for π-π scattering. We improve the rigorous upper bound derived by Łukaszuk and Martin for the π⁰-π⁰ scattering amplitude at the symmetric point. Our principle new tool is the "parametric dispersion relation" of …
