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.
