Possibly New Charmed Baryon States from ${\bar{B}}^0\to p\bar{p}{D}^0$ Decay

We examine the invariant mass spectrum of $D^{0}p$ in $\bar B^0\to p\bar p D^{0}$decaymeasuredbyBABARandfindthatthroughthe2-stepprocessesof$\bar B^0\to {\bf B_c^+}(\to D^{0} p)\bar p$,where${\bf B_c}$ denotes a charmed baryon state, some of the peaks can be identified with the established ${\mathrm{\Sigma }}_c(2800{)}^{+}$, ${\mathrm{\Lambda }}_c(2880{)}^{+}$ and ${\mathrm{\Lambda }}_c(2940{)}^{+}$. Moreover, in order to account for the measured spectrum, it is necessary to introduce a new charmed baryon resonance with $(m,\mathrm{\Gamma })=(3212\pm 20,167\pm 34)$ MeV.
