${{\mathit \Lambda}_{{{c}}}{(2765)}^{+}}$ $~$or ${{\mathit \Sigma}_{{{c}}}{(2765)}}$ $I(J^P)$ = $?(?^{?})$

A broad, statistically significant peak ($997$ ${}^{+141}_{-129}$ events) seen in ${{\mathit \Lambda}_{{{c}}}^{+}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$. However, nothing at all is known about its quantum numbers, including whether it is a ${{\mathit \Lambda}_{{{c}}}^{+}}$ or a ${{\mathit \Sigma}_{{{c}}}}$, or whether the width might be due to overlapping states.
