本文给出了星星实验测量的200 GeV最小偏压d + Au、外围和中心Au+Au碰撞中3粒子Δη-Δη关联的第一个结果.详细描述了分析技术。在中心Au+Au碰撞的双强子关联中，在大Δη处观察到的脊粒子，在三粒子关联中，在测量的Δη-Δη区域上似乎是均匀分布的。这些结果，加上理论模型，应该有助于我们进一步了解脊的基本物理。
We present the first results on 3-particle Δη–Δη correlations in minimum bias d + Au, peripheral and central Au+Au collisions at = 200 GeV measured by the STAR experiment. The analysis technique is described in detail. The ridge particles, observed at large Δη in dihadron correlations in central Au+Au collisions, appear to be uniformly distributed over the measured Δη–Δη region in 3-particle correlation. The results, together with theoretical models, should help further our understanding of the underlying physics of the ridge.
