| Description: |
Using +− annihilation data corresponding to a total integrated luminosity of 7.33 fb−1 collected at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, we provide the first amplitude analysis and absolute branching fraction measurement of the hadronic decay +→00+. The branching fraction of +→00+ is determined to be (1.86±0.06stat±0.03syst)%. Combining the ℬ[+→(→00)+] obtained in this Letter and the world average of ℬ[+→(→+−)+], we measure the relative branching fraction ℬ(→00)/ℬ(→+−)=(0.593±0.023stat±0.014syst±0.016), where the third error is due to the uncertainty of the ℬ(+→+,→+−). Our result deviates from the Particle Data Group value by more than 3. Furthermore, the asymmetry of the branching fractions of +→0*(892)+ and +→0*(892)+, ({ℬ[+→0*(892)+]−ℬ[+→0*(892)+]}/{ℬ[+→0*(892)+]+ℬ[+→0*(892)+]}), is determined to be (−14.5 ±5.1stat ±1.8syst)%. |
