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

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.$~$3 in the note on Charmed Baryons. The quantum numbers given above come from this presumption but have not been measured.
 ${{\mathit \Xi}_{{c}}^{'+}}$ MASS $2578.4 \pm0.5$ MeV
 ${{\mathit \Xi}_{{c}}^{'+}}–{{\mathit \Xi}_{{c}}^{+}}$ MASS DIFFERENCE $110.5 \pm0.4$ MeV
 ${{\mathit \Xi}_{{c}}^{'+}}–{{\mathit \Xi}_{{c}}^{'0}}$ MASS DIFFERENCE $-0.8 \pm0.6$ MeV
The ${{\mathit \Xi}_{{c}}^{'+}}-{{\mathit \Xi}_{{c}}^{+}}$ mass difference is too small for any strong decay to occur.
