Abstract

Assuming a high-momentum equality of certain time-ordered products of vector and axial vector currents between low-lying states, we obtain several interesting results. Matrix elements between vacuum states lead to Weinberg-type sum rules previously obtained by others. Application to matrix elements between the vacuum and the ρ+-meson leads to information on the isovector form factors of the ρ+.
