Abstract

Quantum-correlated View the MathML source decays collected by the CLEO-c experiment are used to perform first measurements of F+, the fractional CP -even content of the self-conjugate decays D→∏+∏−∏0 and D→K+K−∏0. Values of 0.968±0.017±0.006 and 0.731±0.058±0.021 are obtained for ∏+∏−∏0 and K+K−∏0, respectively. It is demonstrated how modes of this sort can be cleanly included in measurements of the unitarity triangle angle γ using B∓→DK∓ decays. The high CP -even content of D→∏+∏−∏0, in particular, makes this a promising mode for improving the precision on γ.
