基于BOSS软件框架,利用BESIII合作组产生的400 M单举ψ（3686）事例,研究在BESIII探测器上实现测量到Xc J→ηη’分支比的可能性.以无信号事例的单举ψ（3686）样本为背景样本,以纯信号蒙特卡罗事例为信号样本,控制信号事例,在分别假设观测到Xc J→ηη’衰变过程信号显著水平为3σ和5σ的情况下,得到该过程对应的分支比.

Based on BOSS framework, by using the 400 M inclusive ψ(3686) events produced by BESIII data production group, the possibility was studied that of measurement the branching fraction of χc J →ηη’ at BESIII. By using 400 M inclusive ψ(3686) events as background sample and exclusive Monte Carlo sample as signal sample, assuming the signal significant to be 3σ and 5σ by controlling the signal event, the ...
