Abstract

A method to evaluate high-energy contributions to current-algebra sum rules by combining them with finite-energy sum rules is suggested. Applications are made to the Adler-Weisberger-type sum rules for the $\ensuremath{\pi}\ensuremath{-}\ensuremath{\pi}$ and the $K\ensuremath{-}\ensuremath{\pi}$ systems, and to various sum rules for the pion photoproduction process. It is shown that the former sum rules can be approximately satisfied without requiring very large scalar contributions. Some interesting results are found for the latter sum rules.
