Quantum-correlated measurements of D → K S0 π + π − π 0 decays and consequences for the determination of the CKM angle γ

Abstract

Abstract We perform quantum-correlated measurements of the decay D → K S0 π + π − π 0 using a data sample corresponding to an integrated luminosity of 0.82 fb−1 collected at the ψ(3770) resonance by the CLEO-c detector. The value of the CP -even fraction F + is determined to be 0.238 ± 0.012 ± 0.012. The strong-phase differences are also measured in different regions of K S0 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 S0 π + π − π 0)K ± decays is also discussed.
