Intermediate-Coupling Models for Hyperon Isobars

Two intermediate-coupling groups valid for both the nucleon and the hyperon isobars are suggested. For the nucleon isobars these reduce to the group $\mathrm{SU}\left(4\right)\mathrm{}$. Predictions of these groups for the hyperon coupling-constant ratios and magnetic moments are obtained. It is found that, in general, the results are consistent with the static $\mathrm{SU}\left(6\right)\mathrm{}$ theory.
