Abstract
We study JP=32− baryon resonances as generated by chiral coupled-channel dynamics in the χ-BS(3) approach. Parameter-free results are obtained in terms of the Weinberg–Tomozawa term predicting the leading s-wave interaction strength of Goldstone bosons with baryon-decuplet states. In the ‘heavy’ SU(3) limit with mπ=mK∼500 MeV the resonances turn into bound states forming a decuplet and octet representation of the SU(3) group. Using physical masses the mass splitting are remarkably close to the empirical pattern.
