${{\boldsymbol \Xi}_{{b}}^{0}}$ $I(J^P)$ = $1/2(1/2^{+})$ I, J, P need confirmation.

In the quark model, ${{\mathit \Xi}_{{b}}^{0}}$ and ${{\mathit \Xi}_{{b}}^{-}}$ are an isodoublet ($\mathit usb$, $\mathit dsb$) state; the lowest ${{\mathit \Xi}_{{b}}^{0}}$ and ${{\mathit \Xi}_{{b}}^{-}}$ ought to have $\mathit J{}^{P} = 1/2{}^{+}$. None of $\mathit I$, $\mathit J$, or ${}^{P}$ have actually been measured.
