摘要：
The charge radii and magnetic moments of all the light and strange baryons are investigated within the framework of a constituent-quark model based on Goldstone-boson-exchange dynamics. Following the pointform approach to relativistic quantum mechanics, the calculations are performed in a manifestly covariant manner. Relativistic (boost) effects have a sizeable influence on the results. The direct predictions of the constituent-quark model are found to fall remarkably close to the available experimental data.
