Abstract

We report the first determination of the relative strong-phase difference between D0→KS,L0K⁺K^- and D⊃̄0→KS, L0K⁺K^-. In addition, we present updated measurements of the relative strong-phase difference between D0→KS, L0π⁺π^- and D⊃̄0→KS,L0π ⁺π^-. Both measurements exploit the quantum coherence between a pair of D0 and D⊃̄0 mesons produced from ψ(3770) decays. The strong-phase differences measured are important for determining the Cabibbo-Kobayashi-Maskawa angle γ/Φ₃ in B ^-→K^-D⊃0 decays, where D⊃0 is a D0 or D⊃̄0 meson decaying to KS0h⁺h^- (h=π, K), in a manner independent of the model assumed to describe the D0→KS0h ⁺h^- decay. Using our results, the uncertainty in γ/Φ₃ due to the error on the strong-phase difference is expected to be between 1.7° and 3.9° for an analysis using B ^-→K^-D⊃0, D⊃0→KS0π⁺π ^- decays, and between 3.2° and 3.9° for an analysis based on B^-→K^-D⊃0, D⊃0→KS0K⁺K ^- decays. A measurement is also presented of the CP-odd fraction, F_-, of the decay D0→KS0K⁺K^- in the region of the Φ→K⁺K^- resonance. We find that in a region within 0.01GeV2/c4 of the nominal Φ mass squared F_->0.91 at the 90% confidence level.
