BOTTOM BARYONS($\mathit B$ = $-1$) ${{\mathit \Lambda}_{{b}}^{0}}$ = ${{\mathit u}}{{\mathit d}}{{\mathit b}}$ , ${{\mathit \Xi}_{{b}}^{0}}$ = ${{\mathit u}}{{\mathit s}}{{\mathit b}}$ , ${{\mathit \Xi}_{{b}}^{-}}$ = ${{\mathit d}}{{\mathit s}}{{\mathit b}}$ , ${{\mathit \Omega}_{{b}}^{-}}$ = ${{\mathit s}}{{\mathit s}}{{\mathit b}}$

#### ${{\mathit \Xi}_{{b}}^{0}}$ , ${{\mathit \Xi}_{{b}}^{-}}$

$I(J^P)$ = $1/2(1/2^{+})$ 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.
