Query: 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 $\bar B^0\to p\bar p
D^{0}$ decay measured by BABAR and find that through the 2-step processes of
$\bar B^0\to {\bf B_c^+}(\to D^{0} p)\bar p$, where ${\bf B_c}$ denotes a
charmed baryon state, some of the peaks can be identified with the established
$\Sigma_c(2800)^+$, $\Lambda_c(2880)^+$ and $\Lambda_c(2940)^+$. Moreover, in
order to account for the measured spectrum, it is necessary to introduce a new
charmed baryon resonance with $(m,\,\Gamma)=(3212\pm 20,\,167\pm 34)$ MeV.
