Magnetic moments of exotic pentaquarks in the chiral quark-soliton model

Abstract

We investigate the magnetic moments of the baryon antidecuplet within the framework of the chiral quark-soliton model in the chiral limit in a ``\emph{model-independent}'' approach. Sum rules for the magnetic moments are derived. The magnetic moment of $Θ^{+}$ is found to be about $0.2\sim 0.3 μ_{N}$.
