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

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 ${{\mathit \Sigma}_{{{c}}}}$.
