LHC上Pb-Pb碰撞的统计模型

The statistical model in Pb-Pb collisions at the LHC

A. Andronic, P. Braun-Munzinger, K. Redlich, J. Stachel

摘要:

我们简要回顾了强子产生的热模型的预测与RHIC的最新数据的比较,并将计算外推到LHC能量。我们的主要重点是将模型预测与LHC的ALICE最近发布的数据进行比较。这种比较揭示了质子和反质子的明显异常,我们简要讨论。我们还表明,我们的统计强子化预测J/ $ψ$生产同意非常好的最新的大型强子对撞机的数据,贷款支持的图片,其中有完整的夸克-胶子等离子体(QGP)的统计产生J/ $ψ$介子在相边界。

英文摘要:

We briefly review the predictions of the thermal model for hadron production in comparison to latest data from RHIC and extrapolate the calculations to LHC energy. Our main emphasis is to confront the model predictions with the recently released data from ALICE at the LHC. This comparison reveals an apparent anomaly for protons and anti-protons which we discuss briefly. We also demonstrate that our statistical hadronization predictions for J/$ψ$ production agree very well with the most recent LHC data, lending support to the picture in which there is complete charmonium melting in the quark-gluon plasma (QGP) followed by statistical generation of J/$ψ$ mesons at the phase boundary.
