摘要：
It is crucial to determine the spin and parity(J~P) of Z(3900)~± for understanding its structure.We perform a helicity amplitude analysis on Z(3900)~± in the process e~+e~-→π~+π~-J/φ with the hypotheses J~P= 0~-,1~+,1~-,2~+ and 2~-.To estimate the significance of J~P = 1~+ over other hypotheses,we perform a Monte Carlo simulation study,and we also discuss the prospect of measuring the spin parity in the future experiment with a large data sample.
