${{\mathit P}_{{{c {{\overline{\mathit c}}} s}}}{(4338)}^{0}}$ $I(J^P)$ = $0(1/2^{-})$

AAIJ 2023Q determines that spin-parity $\mathit J{}^{P} = 1/2{}^{-}$ is preferred, while spin-parity $\mathit J{}^{P} = 1/2{}^{+}$ is excluded at a 90$\%$ confidence level and spin $\mathit J = 3/2$ hypotheses are discarded.
