We discuss different sources of hadron correlations in relativistic heavy ion collisions. We show that correlations among partons in a quasithermal medium can lead to the correlated emission of hadrons by quark recombination and argue that this mechanism offers a plausible explanation for the dihadron correlations in the few GeV/c momentum range observed in Au+Au collisions at the BNL Relativistic Heavy Ion Collider.
我们讨论了相对论重离子碰撞中强子关联的不同来源。我们表明，准热介质中部分子之间的关联可通过夸克重组导致强子的关联发射，并认为这种机制为在布鲁克海文国家实验室相对论重离子对撞机上金离子与金离子碰撞中观测到的几吉电子伏特每光速动量范围内的双强子关联提供了一个合理的解释。
