An approximation scheme for constructing pi /sup 0/ pi /sup 0/ amplitudes from ACU requirements
The requirements of analyticity, crossing symmetry and unitarity (ACU) are used as input to construct amplitudes for the scattering of neutral pi mesons. They are obtained explicitly as polynomials in certain conformally transformed variables which ensure the correct analyticity structure. Crossing...
