Transverse momentum spectra for charged hadrons and for neutral pions in the range 1 GeV/c<p(T)<5 GeV/c have been measured by the PHENIX experiment at RHIC in Au+Au collisions at root square[s(NN)] = 130 GeV. At high p(T) the spectra from peripheral nuclear collisions are consistent with scaling the spectra from p+p collisions by the average number of binary nucleon-nucleon collisions. The spectra from central collisions are significantly suppressed when compared to the binary-scaled p+p expectation, and also when compared to similarly binary-scaled peripheral collisions, indicating a novel nuclear-medium effect in central nuclear collisions at RHIC energies.
在相对论重离子对撞机（RHIC）上，PHENIX实验测量了金金（Au+Au）对撞中，质心能量平方根√[s(NN)] = 130 GeV时，带电强子和中性π介子在1 GeV/c < p(T) < 5 GeV/c范围内的横向动量谱。在高横向动量下，外围核碰撞的谱与通过二元核子-核子碰撞平均数量对质子-质子（p+p）碰撞谱进行标度一致。与二元标度的p+p预期相比，以及与类似二元标度的外围碰撞相比，中心碰撞的谱都受到显著抑制，这表明在RHIC能量下的中心核碰撞中存在一种新型的核介质效应。
