摘要:
Abstract Using e+e- annihilation data corresponding to an integrated luminosity of 2.93 fb-1 taken at the center-of-mass energy √s=3.773 GeV with the BESIII detector, a joint amplitude analysis is performed on the decays D0→π+π-π+π- and D0→π+π-π0π0(non-η). The fit fractions of individual components are obtained, and large interferences among the dominant components of the decays D0→a1(1260)π, D0→π(1300)π, D0→ρ(770)ρ(770) and D0→2(ππ)S are found in both channels. With the obtained amplitude model, the CP-even fractions of...
