$\Delta \mathit C_{{{\mathit a}_{{{1}}}} {{\mathit \pi}}}$ describes the asymmetry between the rates $\Gamma\mathrm {( {{\mathit B}^{0}} \rightarrow {{\mathit a}_{{{1}}}^{+}} {{\mathit \pi}^{-}})}$ + $\Gamma\mathrm {( {{\overline{\mathit B}}^{0}} \rightarrow {{\mathit a}_{{{1}}}^{-}} {{\mathit \pi}^{+}})}$ and $\Gamma\mathrm {( {{\mathit B}^{0}} \rightarrow {{\mathit a}_{{{1}}}^{-}} {{\mathit \pi}^{+}})}$ + $\Gamma\mathrm {( {{\overline{\mathit B}}^{0}} \rightarrow {{\mathit a}_{{{1}}}^{+}} {{\mathit \pi}^{-}})}$.
