BOTTOM MESONS($\mathit B$ = $\pm1$) ${{\mathit B}^{+}}$ = ${\mathit {\mathit u}}$ ${\mathit {\overline{\mathit b}}}$, ${{\mathit B}^{0}}$ = ${\mathit {\mathit d}}$ ${\mathit {\overline{\mathit b}}}$, ${{\overline{\mathit B}}^{0}}$ = ${\mathit {\overline{\mathit d}}}$ ${\mathit {\mathit b}}$, ${{\mathit B}^{-}}$ = ${\mathit {\overline{\mathit u}}}$ ${\mathit {\mathit b}}$, similarly for ${{\mathit B}^{*}}$ 's

#### ${{\mathit B}_{{1}}{(5721)}^{+}}$

$I(J^P)$ = $1/2(1^{+})$ I, J, P need confirmation.
Quantum numbers shown are quark-model predictions.
