 $\Delta \mathit A_{CP}$ = $\mathit A_{CP}$( ${{\mathit K}^{+}}{{\mathit K}^{-}}$ ) $−$ $\mathit A_{CP}$( ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ ) $-0.00161 \pm0.00029$
${{\boldsymbol D}^{0}}$ $\boldsymbol CPT$-VIOLATING DECAY-RATE ASYMMETRIES
 $\mathit A_{\mathit CPT}({{\mathit K}^{\mp}}{{\mathit \pi}^{\pm}}$) in ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit \pi}^{+}}$ , ${{\overline{\mathit D}}^{0}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit \pi}^{-}}$ $0.008 \pm0.008$
Most decay modes (other than the semileptonic modes) that involve a neutral ${{\mathit K}}$ meson are now given as ${{\mathit K}_S^0}$ modes, not as ${{\overline{\mathit K}}^{0}}$ modes. Nearly always it is a ${{\mathit K}_S^0}$ that is measured, and interference between Cabibbo-allowed and doubly Cabibbo-suppressed modes can invalidate the assumption that 2$~\Gamma ({{\mathit K}_S^0}$ ) = $\Gamma ({{\overline{\mathit K}}^{0}}$).
