Using a data sample of e+e- collisions corresponding to an integrated luminosity of 7.93 fb-1 collected with the BESIII detector at the center-of-mass energy 3.773 GeV, we perform the first amplitude analysis of the decay D+→KS0KS0π+. The absolute branching fraction of D+→KS0KS0π+ is measured to be (2.97±0.09stat±0.05syst)×10-3. The dominant intermediate process is D+→KS0K∗(892)+, whose branching fraction is determined to be (8.72±0.28stat±0.15syst)×10-3, including all the K∗(892)+ decays.

Abstract

Using a data sample of e+e- collisions corresponding to an integrated luminosity of 7.93 fb-1 collected with the BESIII detector at the center-of-mass energy 3.773 GeV, we perform the first amplitude analysis of the decay D+→KS0KS0π+. The absolute branching fraction of D+→KS0KS0π+ is measured to be (2.97±0.09stat±0.05syst)×10-3. The dominant intermediate process is D+→KS0K∗(892)+, whose branching fraction is determined to be (8.72±0.28stat±0.15syst)×10-3, including all the K∗(892)+ decays.
