${{\boldsymbol \Lambda}_{{c}}{(2625)}^{+}}$ $I(J^P)$ = $0(3/2^{-})$

The spin-parity has not been measured but is expected to be ${}^{}3/2{}^{-}$: this is presumably the charm counterpart of the strange ${{\mathit \Lambda}{(1520)}}$.

${{\mathit \Lambda}_{{c}}{(2625)}^{+}}$ MASS

$2628.11 \pm0.19$ MeV (S = 1.1)

${{\mathit \Lambda}_{{c}}{(2625)}^{+}}–{{\mathit \Lambda}_{{c}}^{+}}$ MASS DIFFERENCE

$341.65 \pm0.13$ MeV (S = 1.1)

${{\mathit \Lambda}_{{c}}{(2625)}^{+}}$ WIDTH

Decay Modes

${{\mathit \Lambda}_{{c}}^{+}}{{\mathit \pi}}{{\mathit \pi}}$ and its submode ${{\mathit \Sigma}{(2455)}}{{\mathit \pi}}$ are the only strong decays allowed to an excited ${{\mathit \Lambda}_{{c}}^{+}}$ having this mass.
