Using e+e−annihilation data corresponding to an integrated luminosity of 2.93 fb−1taken 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)Sare observed in both channels.With the obtained amplitude model,the CP-even fractions of D0→π+π−π+π−and D0→π+π−π0π0(non-η)are determined to be(75.2±1.1stat.±1.5syst.)%and(68.9±1.5stat.±2.4syst.)%,respectively.The branching fractions of D0→π+π−π+π−and D0→π+π−π0π0(non-η)are measured to be(0.688±0.010stat.±0.010syst.)%and(0.951±0.025stat.±0.021syst.)%,respectively.The amplitude analysis provides an important model for the binning strategy in measuring the strong phase parameters of D0→4πwhen used to determine the CKM angleγ(ϕ3)via the B−→DK−decay. 展开更多

- 摘要 Using e+e−annihilation data corresponding to an integrated luminosity of 2.93 fb−1taken 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)Sare observed in both channels.With the obtained amplitude model,the CP-even fractions of D0→π+π−π+π−and D0→π+π−π0π0(non-η)are determined to be(75.2±1.1stat.±1.5syst.)%and(68.9±1.5stat.±2.4syst.)%,respectively.The branching fractions of D0→π+π−π+π−and D0→π+π−π0π0(non-η)are measured to be(0.688±0.010stat.±0.010syst.)%and(0.951±0.025stat.±0.021syst.)%,respectively.The amplitude analysis provides an important model for the binning strategy in measuring the strong phase parameters of D0→4πwhen used to determine the CKM angleγ(ϕ3)via the B−→DK−decay.
