First evidence for a charm radial excitation, $D^{*}'$

Using D$^{*+}$ mesons exclusively reconstructed in the DELPHI detector at LEP, an excess of $66\pm14(\mbox{stat.})$ events is observed in the D$^{*+}\pi^+\pi^-$ final state with a mass of $2637\pm2(\mbox{stat.})\pm6(\mbox{syst.})$~MeV/$c^2$ and a full width smaller than 15~MeV/$c^2$ (95\% C.L.).

Sumario:Using D$^{*+}$ mesons exclusively reconstructed in the DELPHI detector at LEP, an excess of $66\pm14(\mbox{stat.})$ events is observed in the D$^{*+}\pi^+\pi^-$ final state with a mass of $2637\pm2(\mbox{stat.})\pm6(\mbox{syst.})$~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.
