Abstract
An alternative derivation based on the technique of asymptotic symmetry is given for the pion-pion scattering sum rule. We propose a new asymptotic symmetry hypothesis in terms of the proper amplitudes, which has the merit of narrowing the discrepancy between experiment and the Adler sum rule.
