] | We consider various possible identifications of the quantum numbers of the resonance D(2637) recently observed by DELPHI in the $D^*\pi\pi$ channel. We argue that in spite of a good agreement of the measured mass with the quark-model prediction for the radial excitation, a total width as small as $\le 15$ MeV is hardly... |
