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

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.

$\Gamma_{1}$

${{\mathit \Omega}_{{c}}^{0}}{{\mathit \gamma}}$
