论文摘要
我们为$ψ\toδ\barδ$，$δ\ topπ$的部分波分析得出了张量振幅，以及螺旋帧内的pπ$，以及具有相同最终状态的其他衰减序列的振幅。这些公式对于测量$ψ$衰减到$ p \ bar {p}π^+π^ - $最终状态的实验是实用的，例如besiii，其最近收集的巨大$ j/ψ$和$ sth $和$ψ$和$ψ（2s）$数据样本。
We have derived the tensor amplitudes for partial wave analysis of $ψ\toΔ\barΔ$, $Δ\to p π$ within the helicity frame, as well as the amplitudes for the other decay sequences with same final states. These formulae are practical for the experiments measuring $ψ$ decaying into $p \bar{p}π^+ π^-$ final states, such as BESIII with its recently collected huge $J/ψ$ and $ψ(2S)$ data samples.
