ISOSPIN ASYMMETRY

$\Delta _{0-}$ is defined as
${\Gamma\mathrm {({{\overline{\mathit B}}^{0}} \rightarrow {{\mathit f}_{{{d}}}})}–\Gamma\mathrm {({{\mathit B}^{-}} \rightarrow {{\mathit f}_{{{u}}}})}\over \Gamma\mathrm {({{\overline{\mathit B}}^{0}} \rightarrow {{\mathit f}_{{{d}}}})}+\Gamma\mathrm {({{\mathit B}^{-}} \rightarrow {{\mathit f}_{{{u}}}})}}$,
the isospin asymmetry of inclusive neutral and charged B decay.

$\Delta _{{{\mathit \rho}} {{\mathit \gamma}}}$ = $\Gamma ({{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit \rho}^{+}}{{\mathit \gamma}}$) $/$ (2 $\cdot{}$ $\Gamma ({{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit \rho}^{0}}{{\mathit \gamma}}$) ) $−$ 1
