基于关联度概念 ,建立了可以分别检测高阶集合流的方位角关联、横向动量模关联和横向关联的新方法 .采用新方法分别分析了 1 2AGeVAr +BaI2 碰撞的Bevalac流光室 4π实验事件中末态粒子分布的方位角关联与粒子横向动量模的关联对高阶集合流关联的贡献 .研究表明 :对于这组碰撞实验 ,末态粒子分布的方位角关联相对横向动量模的关联在高阶集合流关联中起主要作用 ;末态粒子横向动量模的关联不但可以使粒子群高阶关联的强度有所增加 ,而且还为在更为狭窄的区间上确定集合流集体性的范围提供了重要信息 .
Based on the concept of degree of association, a new method for detecting the azimuthal correlation, lateral momentum mode correlation and lateral correlation of high-order set flows was established respectively. The new method was used to analyze the influence of 4AG experiment of Bevalac streamer chamber with 12AGeVAr + BaI2 collision The results show that for this set of collisions experiments, the correlation of the azimuthal relative lateral momentum model of the final particle distribution in the higher order set Flow association plays a major role. The correlation of the final particle lateral momentum model not only increases the intensity of high-order correlation of particle swarm, but also provides important information for determining the range of collective flow in a narrower interval .
