Magnetic moments of the exotic pentaquark baryons within the chiral quark-soliton model

Abstract

We present in this talk recent results of the magnetic moments of the baryon antidecuplet within the framework of the chiral quark-soliton model in the chiral limit. The dynamic parameters of the model are fixed by using the experimental data for those of the baryon octet. Sum rules for the magnetic moments are derived. We found that the magnetic moments of the baryon antidecuplet have opposite signs to their charges. The magnetic moments of the neutral baryon antidecuplet turn out to be compatible with zero.
