Abstract We study heavy–light meson resonances with quantum numbers J P =0 + and J P =1 + in terms of the non-linear chiral SU(3) Lagrangian. At leading order a parameter-free prediction is obtained for the scattering of Goldstone bosons off heavy–light pseudo-scalar and vector mesons. The recently announced narrow open-charm states observed by the BABAR and CLEO Collaborations are reproduced. We suggest the existence of states that form an anti-triplet and a sextet representation of the SU(3) group. In particular, so far unobserved narrow isospin-singlet states with negative strangeness are predicted. The open-beauty states with ( I , S )=(0,−1) are anticipated at 5761 MeV ( J P =0 + ) and 5807 MeV ( J P =1 + ). For the anti-triplet states our results differ most significantly from predictions that are based on the chiral quark model in the open-beauty sector. Strongly bound 0 + - and 1 + -states with ( I , S )=(0,1) at 5643 and 5690 MeV are predicted.
