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