$a We study heavy-light baryon resonances with quantum numbers J(P) = 1/2(-) in terms of the nonlinear chiral SU(3) Lagrangian. Within the chi-BS(3) approach a parameter-free leading order prediction is obtained for the scattering of Goldstone bosons off heavy-light baryon resonances with J(P) = 1/2(+). The three states Lambda(cl)(2593), Lambda(c0)(2880) and Xi(c1)(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 (I, S) (1/2 +1) are anticipated 463 -1
