This would presumably be an isospin-1/2 particle, a $\mathit ccu$ ${{\mathit \Xi}_{{cc}}^{++}}$ and a $\mathit ccd$ ${{\mathit \Xi}_{{cc}}^{+}}$. However, opposed to the evidence cited below, the BABAR experiment has found no evidence for a ${{\mathit \Xi}_{{cc}}^{+}}$ in a search in ${{\mathit \Lambda}_{{c}}^{+}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ and ${{\mathit \Xi}_{{c}}^{0}}{{\mathit \pi}^{+}}$ modes, and no evidence of a ${{\mathit \Xi}_{{cc}}^{++}}$ in ${{\mathit \Lambda}_{{c}}^{+}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}{{\mathit \pi}^{+}}$ and ${{\mathit \Xi}_{{c}}^{0}}{{\mathit \pi}^{+}}{{\mathit \pi}^{+}}$ modes (AUBERT,B 2006D). Nor have the BELLE (CHISTOV 2006 , KATO 2014 ) or LHCb (AAIJ 2013CD) experiments found any evidence for this state.
