Abstract

By using 6.32 fb⁻¹ of data collected with the BESIII detector at center-of-mass energies between 4.178 and 4.226 GeV, we perform an amplitude analysis of the decay Ds+→KS0π+π0 and determine the relative fractions and phase differences of different intermediate processes, which include KS0ρ(770)⁺, KS0ρ(1450)⁺, K^*(892)⁰π⁺, K^*(892)⁺π⁰, and K^*(1410)⁰π⁺. With the detection efficiency based on the amplitude analysis results, the absolute branching fraction is measured to be ℬ(Ds+→KS0π+π0)=(5.43±0.30stat±0.15syst)×10−3.
