${{\boldsymbol \Lambda}_{{c}}{(2880)}^{+}}$ $I(J^P)$ = $0(5/2^{+})$

A narrow peak seen in ${{\mathit \Lambda}_{{c}}^{+}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ and in ${{\mathit p}}{{\mathit D}^{0}}$ . It is not seen in ${{\mathit p}}{{\mathit D}^{+}}$ , and therefore it is a ${{\mathit \Lambda}_{{c}}^{+}}$ and not a ${{\mathit \Sigma}_{{c}}}$.
