Abstract :
We study heavy-light baryon resonances with quantum numbers View the MathML source in terms of the non-linear chiral SU(3) Lagrangian. Within the χ–BS(3) approach a parameter-free leading order prediction is obtained for the scattering of Goldstone bosons off heavy-light baryon resonances with View the MathML source. The three states Λc1(2593), Λc0(2880) and Ξc1(2790) discovered by the CLEO Collaboration are recovered. We suggest the existence of resonance states that form an anti-quindecimplet, two sextet and two anti-triplet representations of the SU(3) group. In particular, narrow states with anomalous isospin (I) and strangeness (S) quantum numbers View the MathML source are anticipated.
