Baryon magnetic moments in the SU(3) chiral quark-soliton model — •M. Praszałowicz, H.-Ch. Kim, K. Goeke, and M.V. Polyakov — Institut für Theoretische Physik II, Ruhr-Universität Bochum, D-44780 Bochum Germany
Magnetic moments of baryons are studied within the chiral quark soliton model with special emphasis on the decuplet of baryons. The model is used to identify all symmetry breaking terms proportional to ms. Sum rules for the magnetic moments are derived. A “model-independent” analysis of the symmetry breaking terms is performed and finally model calculations are presented, which show the importance of the rotational 1/Nc corrections for cranking of the soliton. Flavor structure of the octet magnetic moments in terms of the u, d and s components is studied.
