Abstract

Using a data sample of

𝑒 + 𝑒 -

collisions corresponding to an integrated luminosity of

7.93 f b - 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 + \to 𝐾 0 𝑆 𝐾 0 𝑆 𝜋 +

. The absolute branching fraction of

𝐷 + \to 𝐾 0 𝑆 𝐾 0 𝑆 𝜋 +

is measured to be

(2.97 \pm 0.0 9 s t a t \pm 0.0 5 s y s t) \times 10 - 3

. The dominant intermediate process is

𝐷 + \to 𝐾 0 𝑆 𝐾 * (892) +

, whose branching fraction is determined to be

(8.72 \pm 0.2 8 s t a t \pm 0.1 5 s y s t) \times 10 - 3

, including all the

𝐾 * (892) +

decays.

Study of𝐷+→𝐾0𝑆⁢𝐾*⁢(892)+in𝐷+→𝐾0𝑆⁢𝐾0𝑆⁢𝜋+

我们利用 BESIII 探测器在质量中心能量 3.773 GeV 处收集到的𝑒+𝑒-对撞数据样本（对应于 7.93 fb-1 的综合光度），首次对衰变𝐷+→文献0𝑆𝑆0𝑆𝜋+进行了振幅分析。经测量，𝐷+→0 𝑆𝑆𝜋+的绝对分支分数为（2.97±0.09stat±0.05syst）×10-3。主要的中间过程是𝐷+→𝑆𝑆𝜋+，其分支分数被测定为（8.72±0.28stat±0.15syst）×10-3，其中包括所有的𝐷*(892)+衰变。
