CHARMED BARYONS ($\mathit C$ = $+1$) ${{\mathit \Lambda}_{{{c}}}^{+}}$ = ${{\mathit u}}{{\mathit d}}{{\mathit c}}$ , ${{\mathit \Sigma}_{{{c}}}^{++}}$ = ${{\mathit u}}{{\mathit u}}{{\mathit c}}$ , ${{\mathit \Sigma}_{{{c}}}^{+}}$ = ${{\mathit u}}{{\mathit d}}{{\mathit c}}$ , ${{\mathit \Sigma}_{{{c}}}^{0}}$ = ${{\mathit d}}{{\mathit d}}{{\mathit c}}$ , ${{\mathit \Xi}_{{{c}}}^{+}}$ = ${{\mathit u}}{{\mathit s}}{{\mathit c}}$ , ${{\mathit \Xi}_{{{c}}}^{0}}$ = ${{\mathit d}}{{\mathit s}}{{\mathit c}}$ , ${{\mathit \Omega}_{{{c}}}^{0}}$ = ${{\mathit s}}{{\mathit s}}{{\mathit c}}$

${{\mathit \Omega}_{{{c}}}{(2770)}^{0}}$ $I(J^P)$ = $0(3/2^{+})$

The natural assignment is that this goes with the ${{\mathit \Sigma}_{{{c}}}{(2520)}}$ and ${{\mathit \Xi}_{{{c}}}{(2645)}}$ to complete the lowest mass $\mathit J{}^{P}$ = ${}^{}3/2{}^{+}$ SU(3) sextet, part of the SU(4) 20-plet that includes the ${{\mathit \Delta}{(1232)}}$. But $\mathit J$ and ${}^{P}$ have not been measured.

${{\mathit \Omega}_{{{c}}}{(2770)}^{0}}$ MASS   $2765.9 \pm2.0$ MeV (S = 1.2)

${{\mathit \Omega}_{{{c}}}{(2770)}^{0}}–{{\mathit \Omega}_{{{c}}}^{0}}$ MASS DIFFERENCE   $70.7 {}^{+0.8}_{-0.9}$ MeV

Decay Modes
The ${{\mathit \Omega}_{{{c}}}{(2770)}^{0}}-{{\mathit \Omega}_{{{c}}}^{0}}$ mass difference is too small for any strong decay to occur.
