${{\mathit \Xi}_{{{b}}}^{0}}$

$I(J^P)$ = $1/2(1/2^{+})$ 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.
