${{\boldsymbol D}^{0}}$ $\rightarrow$ ${{\boldsymbol K}_S^0}$ ${{\boldsymbol K}^{+}}{{\boldsymbol \pi}^{-}}$ AVERAGE RELATIVE STRONG PHASE $\delta {}^{ {{\boldsymbol K}_S^0} {{\boldsymbol K}} {{\boldsymbol \pi}} }$ INSPIRE search

The quoted value of $\delta $ is based on the same sign $\mathit CP$ phase of ${{\mathit D}^{0}}$ and ${{\overline{\mathit D}}^{0}}$ convention.

1  Uses quantum correlations in ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit D}^{0}}{{\overline{\mathit D}}^{0}}$ at the ${{\mathit \psi}{(3770)}}$, where the signal side ${{\mathit D}}$ decays to ${{\mathit K}_S^0}$ ${{\mathit K}}{{\mathit \pi}}$ and the tag-side ${{\mathit D}}$ decays to ${{\mathit K}}{{\mathit \pi}}$ , ${{\mathit K}}{{\mathit \pi}}{{\mathit \pi}}{{\mathit \pi}}$ , ${{\mathit K}}{{\mathit \pi}}{{\mathit \pi}^{0}}$ , and 10 additional $\mathit CP$-even, $\mathit CP$-odd, and mixed $\mathit CP$ modes involving ${{\mathit K}_S^0}$ or ${{\mathit K}_L^0}$ .
