Charmed meson resonances from chiral coupled‐channel dynamics

Charmed meson resonances with quantum numbers JP = 0+ and JP = 1+ are generated in terms of chiral coupled‐channel dynamics. At leading order in the chiral expansion a parameter‐free prediction is obtained for the scattering of Goldstone bosons off charmed 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.
