由硬散射产生的嵌入在大核碰撞中的快部分子探测器表明，部子遭受了巨大的能量损失，产生的介质可能对损失的能量做出集体反应。本文报道了在Sqrt(S_NN)=200GeV的Au+Au和p+p碰撞中，在横向动量p^t_T=4-12GeV/c和相关带电强子(p^a_T=0.5-7GeV/c)下，中性介子触发粒子随相对方位角的变化测量结果。这些数据导致了两个主要的观察结果。首先，低动量强子的相对角分布，其形状变化被解释为对部分子能量损失的中等响应，发现只有在p^T<；7GeV/c时才被修正。在较高的p^T时，数据与未修改或修改得很弱的形状一致，即使对最低测量的p^a_T也是如此。其次，Au+Au相对于p+p(IAA)中与触发粒子相反的强子的伴随产额在大动量下(IAA~0.35-0.5)受到抑制，但小于单粒子核修正因子(R_AA~0.2)。
Fast parton probes produced by hard scattering and embedded within collisions of large nuclei have shown that partons suffer large energy loss and that the produced medium may respond collectively to the lost energy. We present measurements of neutral pion trigger particles at transverse momenta p^t_T = 4-12 GeV/c and associated charged hadrons (p^a_T = 0.5-7 GeV/c) as a function of relative azimuthal angle Delta Phi at midrapidity in Au+Au and p+p collisions at sqrt(s_NN) = 200 GeV. These data lead to two major observations. First, the relative angular distribution of low momentum hadrons, whose shape modification has been interpreted as a medium response to parton energy loss, is found to be modified only for p^t_T<7 GeV/c. At higher p^t_T, the data are consistent with unmodified or very weakly modified shapes, even for the lowest measured p^a_T. This observation presents a quantitative challenge to medium response scenarios. Second, the associated yield of hadrons opposite to the trigger particle in Au+Au relative to that in p+p (I_AA) is found to be suppressed at large momentum (IAA ~ 0.35-0.5), but less than the single particle nuclear modification factor (R_AA ~0.2).
