First determination of the CP content of D→π+π−π+π− and updated determination of the CP contents of D→π+π−π0 and D→K+K−π0

Quantum-correlated ψ(3770)→DD¯ decays collected by the CLEO-c experiment are used to perform a first measurement of F+4π, 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 D→KS0π+π− and...
