Measurements of the CP-even fractions of D 0→ π+ π-π 0 and D 0→ K+ K-π 0 at BESIII. Physical Review D, 111(1), 012007.24700010http://dx.doi.org/10.1103/PhysRevD.111.012007https://hdl.handle.net/20.500.12713/7174The CP-even fractions (F+) of the decays D0→π+π-π0 and D0→K+K-π0 are measured with a quantum-correlated ψ(3770)→DD¯ data sample collected by the BESIII experiment corresponding to an integrated luminosity of 7.93 fb-1. The results are F+π+π-π0=0.9406±0.0055±0.0033 and F+K+K-π0=0.631±0.014±0.011, where the first uncertainties are statistical and the second systematic. These measurements are consistent with the previous determinations, and the uncertainties for F+π+π-π0 and F+K+K-π0 are reduced by factors of 2.6 and 2.6, respectively. The reported results provide important inputs for the precise measurement of the angle γ of the Cabibbo-Kobayashi-Maskawa matrix and indirect CP violation in charm mixing. © 2025 authors.
