Amplitude analysis and branching fraction measurement of the decay D 0 → K S 0 π 0 π 0
- Abstract:
- An amplitude analysis of the decay D0→KS0π0π0 is performed to determine the relative magnitudes and phases of different intermediate processes. The analysis uses e+e− collision data collected at the center-of-mass energy of 3.773 GeV by the BESIII detector corresponding to an integrated luminosity of 20.3 fb−1. The absolute branching fraction of D0→KS0π0π0 is measured to be (1.026 ± 0.008stat.± 0.009syst.)%. The dominant intermediate process is D0→K¯∗8920→KS0π0π0, with a branching fraction of (4.10 ± 0.10stat.± 0.07syst.) × 10−3.
