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

${{\mathit \Xi}_{{{c}}}^{'+}}$ $I(J^P)$ = $1/2(1/2^{+})$

The ${{\mathit \Xi}_{{{c}}}^{'+}}$ and ${{\mathit \Xi}_{{{c}}}^{'0}}$ presumably complete the SU(3) sextet whose other members are the ${{\mathit \Sigma}_{{{c}}}^{++}}$, ${{\mathit \Sigma}_{{{c}}}^{+}}$, ${{\mathit \Sigma}_{{{c}}}^{0}}$, and ${{\mathit \Omega}_{{{c}}}^{0}}$: see Fig.$~$5 in the ``Quark Model'' review. The quantum numbers given above come from this presumption but have not been measured.

${{\mathit \Xi}_{{{c}}}^{'+}}–{{\mathit \Xi}_{{{c}}}^{+}}$ MASS DIFFERENCE   $110.5 \pm0.4$ MeV

${{\mathit \Xi}_{{{c}}}^{'+}}–{{\mathit \Xi}_{{{c}}}^{'0}}$ MASS DIFFERENCE   $-0.5 \pm0.6$ MeV

${{\mathit \Xi}_{{{c}}}^{'+}}$ DECAY MODES
The ${{\mathit \Xi}_{{{c}}}^{'+}}-{{\mathit \Xi}_{{{c}}}^{+}}$ mass difference is too small for any strong decay to occur.
