SU(3) flavor symmetry considerations for the K–N coupled channels system
Original language description
We study the impact of SU(3) flavor symmetry breaking on the properties of dynamically generated Lambda* states within an effective separable potential model describing the coupled channels K(over bar)N system. The model is based on the chiral meson-baryon Lagrangian at next-to-leading order, and constitutes an improvement over a previous model developed by our group, with its applicability being extended to higher energies covering the Lambda(1670) resonance region. It is demonstrated that the ratios of channel couplings to the resonant states can vary dramatically when the flavor breaking is gradually switched off, tracing a path to the restored SU(3) symmetry. We conclude that the couplings determined from physical observables cannot be used to reliably relate a given resonance to a specific flavor multiplet.
