epsilon -meson coupling constants and scale invariance breaking
A general method for obtaining ratios of coupling constants (defined by pole residues) in a way which is completely free of resonance /background separation troubles is devised and applied to the epsilon -meson. Huge discrepancies between previous determinations are shown to arise (i) from inherent...
