Abstract.

We report on a calculation of higher electromagnetic multipole moments of baryons in a non-covariant quark model approach. The employed method is based on the underlying spin-flavor symmetry of the strong interaction and its breaking. We present results on magnetic octupole moments of decuplet baryons and discuss their implications.

  16. For ground-state baryons an allowed operator $\Omega$ must transform according to one of the irreducible representations found in the product $\bar{\mathbf{56}} \times \mathbf{56} = \mathbf{1} + \mathbf{35} + \mathbf{405} + \mathbf{2695}$. Here, the $\mathbf{1}$, $\mathbf{35}$, $\mathbf{405}$, and $\mathbf{2695}$ dimensional representations, are respectively connected with zero-, one-, two-, and three-body operators. Because the $\mathbf{2695}$ occurs only once, there is a unique three-quark magnetic octupole operator.
