Abstract

We determine the fifth-interaction coupling from large-angle high-energy nucleon-nucleon scattering, and extract the $\frac{D}{F}$ value for baryon matrix elements of a current-current product from hyperon decays. Assuming symmetric-nonet conserved vector current, we predict the baryon octet $\frac{D}{F}$ value. The result fits observations to within 30%. The actual baryon masses fix $sin φ \approx \frac{1}{9} - \frac{1}{12}$ for the eighth-component admixture in the fifth-interaction current.
