Transverse momentum spectra of charged hadrons with p(T)<8 GeV/c and neutral pions with p(T)<10 GeV/c have been measured at midrapidity by the PHENIX experiment at BNL RHIC in d+Au collisions at sqrt[s(NN)]=200 GeV. The measured yields are compared to those in p+p collisions at the same sqrt[s(NN)] scaled up by the number of underlying nucleon-nucleon collisions in d+Au. The yield ratio does not show the suppression observed in central Au+Au collisions at RHIC. Instead, there is a small enhancement in the yield of high momentum particles.
在布鲁克海文国家实验室相对论重离子对撞机（BNL RHIC）的PHENIX实验中，于质心能量√[s(NN)] = 200 GeV的d+Au碰撞中，测量了横动量p(T)<8 GeV/c的带电强子以及横动量p(T)<10 GeV/c的中性π介子在中快度处的横动量谱。将测量得到的产额与相同√[s(NN)]下p+p碰撞中的产额进行比较，并根据d+Au中核子-核子碰撞的数量进行缩放。产额比并未显示出在RHIC的中心Au+Au碰撞中观察到的抑制现象。相反，高动量粒子的产额有小幅增强。
