Study of Excited ${\mathrm{\Xi }}_c$ States Decaying into ${\mathrm{\Xi }}_c^0$ and ${\mathrm{\Xi }}_c^{+}$ Baryons

Using a data sample of 980 ${\mathrm{f}\mathrm{b}}^{-1}$ of $e^{+}{e}^{-}$ annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy $e^{+}{e}^{-}$ collider, we report the results of a study of excited ${\mathrm{\Xi }}_c$ states that decay, via the emission of photons and/or charged pions, into ${\mathrm{\Xi }}_c^0$ or ${\mathrm{\Xi }}_c^{+}$ ground state charmed-strange baryons. We present new measurements of the masses of all members of the ${\mathrm{\Xi }}_c^{\mathrm{\prime }}$, ${\mathrm{\Xi }}_c(2645)$, ${\mathrm{\Xi }}_c(2790)$, ${\mathrm{\Xi }}_c(2815)$, and ${\mathrm{\Xi }}_c(2980)$ isodoublets, measurements of the intrinsic widths of those that decay strongly, and evidence of previously unknown transitions.
