BOTTOM, STRANGE MESONS ($\boldsymbol B$ = $\pm1$, $\boldsymbol S$ = $\mp{}$1)

${{\mathit B}_{{s}}^{0}}$ = ${\mathit {\mathit s}}$ ${\mathit {\overline{\mathit b}}}$, ${{\overline{\mathit B}}_{{s}}^{0}}$ = ${\mathit {\overline{\mathit s}}}$ ${\mathit {\mathit b}}$,
similarly for ${{\mathit B}_{{s}}^{*}}$'s
 • ${{\mathit B}_{{s}}^{0}}$ $0(0^{-})$
