We report high statistics measurements of inclusive charged hadron production in Au+Au and p+p collisions at sqrt[s(NN)]=200 GeV. A large, approximately constant hadron suppression is observed in central Au+Au collisions for 5<p(T)<12 GeV/c. The collision energy dependence of the yields and the centrality and p(T) dependence of the suppression provide stringent constraints on theoretical models of suppression. Models incorporating initial-state gluon saturation or partonic energy loss in dense matter are largely consistent with observations. We observe no evidence of p(T)-dependent suppression, which may be expected from models incorporating jet attenuation in cold nuclear matter or scattering of fragmentation hadrons.
我们报告了在(\sqrt{s(NN)} = 200) GeV的金离子与金离子（Au+Au）以及质子与质子（p+p）碰撞中，对包含性带电强子产生的高统计量测量结果。在中心金离子与金离子碰撞中，对于(5 < p_T < 12) GeV/c，观察到了一个大的、近似恒定的强子抑制现象。产额的碰撞能量依赖性以及抑制的中心度和横向动量（(p_T)）依赖性，对抑制的理论模型提供了严格的限制。包含初始态胶子饱和或致密物质中部分子能量损失的模型，在很大程度上与观测结果一致。我们没有观察到与横向动量相关的抑制的证据，而这可能是包含冷核物质中喷注衰减或碎裂强子散射的模型所预期的。
