${{\mathit \Sigma}_{{c}}{(2455)}}$

$I(J^P)$ = $1(1/2^{+})$ 
The angular distribution of ${{\mathit B}^{-}}$ $\rightarrow$ ${{\mathit \Sigma}_{{c}}{(2455)}^{0}}{{\overline{\mathit p}}}$ favors $\mathit J = 1/2$ (as the quark model predicts). $\mathit J = 3/2$ is excluded by more than four standard deviations; see AUBERT 2008BN.
