在vsNN=200 GeV条件下，研究了Au+Au碰撞中（di-）射流破碎产生的高pt带电强子对的方位相关性。每个触发强子（2.5<pT<4.0 GeV/c）的射流伴生强子（1.0<pT<2.5 GeV/c）的分布随碰撞中心性的变化而变化，在形状和产率上都有所不同，表明核碰撞介质对（二）射流破碎过程有显著影响。
Azimuthal correlations of high-pT charged hadron pairs from (di-)jet-fragmentation are studied at mid-rapidity in Au+Au collisions at vsNN=200 GeV. The distribution of jet-associated partner hadrons (1.0<pT<2.5 GeV/c) per trigger hadron (2.5<pT<4.0 GeV/c) is found to vary with collision centrality, both in shape and in yield, indicating a significant effect of the nuclear collision medium on the (di-)jet fragmentation process.
