Abstract
Quantum-correlated View the MathML source decays collected by the CLEO-c experiment are used to perform a first measurement of View the MathML source, the fractional CP -even content of the self-conjugate decay D→π+π−π+π−, obtaining a value of 0.737±0.028. An important input to the measurement comes from the use of View the MathML source and View the MathML source decays to tag the signal mode. This same technique is applied to the channels D→π+π−π0 and D→K+K−π0, yielding View the MathML source and View the MathML source, where the first uncertainty is statistical and the second systematic. These measurements are consistent with those of an earlier analysis, based on CP -eigenstate tags, and can be combined to give values of View the MathML source and View the MathML source. The results will enable the three modes to be included in a model-independent manner in measurements of the unitarity triangle angle γ using B∓→DK∓ decays, and in time-dependent studies of CP violation and mixing in the View the MathML source system.
