摘要：

Assuming the divergence of the strangeness conserving vector current to be proportional to a scalar field, Treiman-Goldberger-like relations are obtained. Using these relations with the parameters of the πN scalar-isovector meson, we estimate the second-class vector contributions to η and Σ leptonic decays, and find that they are of the same order of magnitude as electromagnetic corrections. © 1969.
