Electric and magnetic form factors of strange baryons

Abstract.Predictions for the electromagnetic form factors of the $\Lambda$, $\Sigma$ and $\Xi$ hyperons are presented. The numerical calculations are performed within the framework of the fully relativistic constituent-quark model developed by the Bonn group. The computed magnetic moments compare favorably with the experimentally known values. Most magnetic form factors GM (Q2) can be parameterized in terms of a dipole with cutoff masses ranging from 0.79 to 1.14 GeV.
