Beschreibungen/Notizen

• Using D ∗+ mesons exclusively reconstructed in the DELPHI detector at LEP, an excess of 66±14(stat.) events is observed in the D ∗+π +π − final state with a mass of 2637±2(stat.)±6(syst.) MeV/ c 2 and a full width smaller than 15 MeV/ c 2 (95% C.L.). This signal is compatible with the expected decay of a radially excited D ∗′ ( J P =1 −) meson.
