Abstract

Quantum-correlated measurements of the decay D⁰ → K⁰_{\rm S}π⁺π^-π⁰ are performed using a data sample corresponding to an integrated luminosity of 818 pb^-1 collected at the ψ(3770) resonance by the CLEO-c detector. Preliminary results are presented for the CP-even fraction F₊ and the strong-phase differences of this decay. The value of F₊ is measured to be 0.246 ± 0.018. The strong-phase differences are measured in different regions of K⁰_{\rm S}π⁺π^-π⁰ phase space by binning around the intermediate resonances present. The potential sensitivity of the results for determining the CKM angle γ from B^±~→~D(K⁰_{\mathrm S}π⁺π^-π⁰)K^± decay using the data collected by the Belle detector is also shown.
