Two-particle azimuthal correlation functions are presented for charged hadrons produced in Au+Au collisions at the Relativistic Heavy Ion Collider (sqrt [s(NN)]=130 GeV). The measurements permit determination of elliptic flow without event-by-event estimation of the reaction plane. The extracted elliptic flow values (v2) show significant sensitivity to both the collision centrality and the transverse momenta of emitted hadrons, suggesting rapid thermalization and relatively strong velocity fields. When scaled by the eccentricity of the collision zone epsilon, the scaled elliptic flow shows little or no dependence on centrality for charged hadrons with relatively low p(T). A breakdown of this epsilon scaling is observed for charged hadrons with pT >1.0 GeV/c.
给出了相对论重离子对撞机（(\sqrt{s_{NN}} = 130) GeV）金离子与金离子碰撞中产生的带电强子的两粒子方位角关联函数。这些测量使得无需对反应平面进行逐个事件估计就能确定椭圆流。提取的椭圆流值（(v_2)）对碰撞中心度和发射强子的横向动量都表现出显著的敏感性，这表明快速热化和相对较强的速度场。当用碰撞区域的偏心率(\epsilon)进行标度时，对于相对低横向动量（(p_T)）的带电强子，标度化的椭圆流对中心度几乎没有或没有依赖性。对于横向动量(p_T > 1.0) GeV/c的带电强子，观察到这种(\epsilon)标度关系的破坏。
