Résumé

We report a precise measurement of the masses of the Ξ_c (2645) and Ξ_c (2815) baryons using a data sample of 414 fb^-1 collected by the Belle Collaboration at the KEKB e⁺ e^- collider. The states Ξ_c (2645)^{0, +} are observed in the Ξ_c^{+, 0} π^{-, +} decay modes, while the Ξ_c (2815)^{0, +} are reconstructed in the Ξ_c (2645)^{+, 0} π^{-, +} decay modes. The following mass splittings are determined: m_{Ξc (2645)+} - m_{Ξc (2645)0} = (- 0.1 ± 0.3 (stat) ± 0.6 (syst)) MeV / c² and m_{Ξc (2815)+} - m_{Ξc (2815)0} = (- 3.4 ± 1.9 (stat) ± 0.9 (syst)) MeV / c² with a much better precision than the current world averages. We also observe a new decay mode, Ξ_c (2980)^{0, +} → Ξ_c (2645)^{+, 0} π^{-, +}.
