"Figure 3_1" of "Azimuthal anisotropy and correlations at large transverse momenta in p + p and Au + Au collisions at s(NN)**(1/2) = 200-GeV."

Upper panel, Azimuthal distributions of associated particles for trigger particles in-plane (squares) and out-of-plane (triangles) for Au+Au collisions at centrality 20-60%. Open symbols are reflections of solid symbols around $\Delta \phi$ = 0 and $\Delta \phi$ = $\pi$. Elliptic flow contribution is shown by dashed lines. Lower panel, Distributions after substracting elliptic flow, and the corresponding measurement in p + p collisions (histogram).上图展示了20%-60%中心度（Centrality）金核-金核（Au+Au）碰撞中，以平面内触发粒子（Trigger Particles，方块标记）和平面外触发粒子（Trigger Particles，三角标记）为参考的关联粒子（Associated Particles）方位角分布（Azimuthal Distributions）。其中空心符号为实心符号关于Δφ=0与Δφ=π的镜像分布。椭圆流（Elliptic Flow）的贡献由虚线呈现。下图为扣除椭圆流后的分布，以及质子-质子（p+p）碰撞中的对应测量结果（以直方图形式展示）。
