D-wave baryon resonances with charm from coupled-channel dynamics Original Research Article

Identifying the zero-range exchange of vector mesons as the driving force for the s-wave scattering of pseudo-scalar mesons off the baryon ground states, the spectrum of View the MathML source molecules is computed. We predict a strongly bound 15-plet of C=−1 states. A narrow crypto-exotic octet of charm-zero states is foreseen. In the C=+1 sector a sextet of narrow resonances is formed due to the interaction of D mesons with the baryon decuplet. A strongly bound triplet of double-charm states is a consequence of coupled-channel dynamics driven by the D mesons.
