Weak-Interaction Predictions ofR(11)

Further consideration is given to $R\left(11\right)\mathrm{}$ as a possible alternative to $\mathrm{SU}\left(6\right)\mathrm{}$; in particular, we look for predictions concerning weak-interaction currents. Because of indeterminacy in the definition of the physical baryons, a further condition is needed to obtain a significant prediction; time-reversal invariance furnishes such a condition. The prediction $3f^2+d^2=\frac{9}{8}$ then results for the parameters describing the axial-vector octet. Combination of this result with the experimental value of $\frac{{\mu }_p}{{\mu }_n}$ yields ${\left(\frac{G_A}{G_V}\right)}_{n\to p}=1.17\mathrm{}$, in complete agreement with the experimental value 1.18±0.02.
