解除限制开始的NA49证据

NA49 evidence for the onset of deconfinement

V. Friese

摘要:

我们审查的NA49合作的背景下,其光束能量扫描计划所获得的实验结果。粒子产额和谱分布的数据表明,在束流能量约为30AGeV的重核中心碰撞中,首次出现了去禁闭相变.强子弦输运模型以及强子气体模型无法描述所观察到的能量依赖性,除非包括额外的参数或未测量的状态。

英文摘要:

We review the experimental results obtained by the NA49 collaboration in the context of its beam energy scan programme. The data on particle yields and spectral distributions suggest that the deconfinement phase transition is first reached in central collisions of heavy nuclei at about 30A GeV beam energy. Hadron-string transport models as well as the hadron gas model fail to describe the observed energy dependences unless additional parameters or unmeasured states are included.
