| Abstract: | The production of excited charm mesons has been observed with the ZEUS detector at HERA. Neutral orbitally excited P-wave charm mesons have been reconstructed in the D*±π∓ final state and the charm-strange meson  was found in the  final state. The fraction of D*± mesons originating from the decays of these mesons has been calculated and converted to the rate of c quarks hadronising as the excited charm mesons. A search for radially excited charm mesons in the D*±π+π- final state has also been performed. The results are compared with those obtained in e+e- annihilations. |
