论文摘要
在$ e^+e^ - $ nihihilation实验中，对$ z_ {cs} $异国情调的最新观察进行了极化分析，并在将来测量其旋转量子数的动机。从非极化电子和正电子束开始，研究了$ z_ {cs} $状态及其衰减角分布模式的偏振转移。建议一些可观察到的物质来确定自旋均衡量子数。蒙特卡洛事件的合奏用于显示一些特殊的时刻分布，以表现出不同的$ z_ {cs} $旋转方案。
A polarization analysis is performed for the recent observation of $Z_{cs}$ exotic state in the $e^+e^-$ annihilation experiment with motivation for measuring its spin quantum number in the future. Starting with the unpolarized electron and positron beam, the polarization transfer to the $Z_{cs}$ state and its decay angular distribution patterns are investigated. Some observables are suggested for determination of the spin parity quantum numbers. An ensemble of Monte-Carlo events are used to show some moment distributions special for manifestation of the different $Z_{cs}$ spin scenarios.
