Abstract
Quantum-correlated measurements of the decay D 0 → K S 0 π + π − π 0 are performed with 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 K S 0 π + π − π 0 phase space by binning around the intermediate resonances present. The potential sensitivity of the results for determining the CKM angle γ from B ± → D(K S 0 π + π − π 0 )K ± decays using data collected by the Belle detector is also shown. c Copyright owned by the author(s) under the terms of the Creative Commons
