摘要
PHENIX 合作组测量了 、Al 和 Au 碰撞在 GeV 下的高- 双强子关联。这些关联源于喷流间与喷流内关联，因而对初态和末态的非微扰效应均敏感。作为伴强子垂直于触发强子的横向动量分量的 分布，对初态和末态横向动量敏感。这些分布作为 （伴强子相对于触发强子的纵向动量分数）的函数被多重微分测量。对碎裂横向动量敏感的近侧 宽度，在 Au、Al 与 之间未显示显著展宽。发现远侧非微扰 宽度在 Au 中相比 有所展宽；然而，与 碰撞相比，Al 中无显著展宽。数据还表明远侧 展宽是相互作用中二元核子-核子碰撞数 的函数。讨论了这些结果关于初态和末态横向动量展宽以及部分子在核中的能量损失等核效应方面的潜在意义。
