Abstract
A primary universal vector and axial-vector interaction theory is proposed for strong-interaction phenomena. It is shown that such a hypothesis leads to a definite relation between vector and pseudoscalar coupling constants, which predict the - and -wave pion-nucleon scattering lengths, in good agreement with experiments. The ratio of -meson to -meson masses is also predicted, which agrees well with the observed value.
