标题： Baryon-Strangeness correlations in Parton/Hadron transport model for Au + Au collisions at \sqrt{s_{NN}} = 200 GeV

摘要： 重子- strangeness 相关性（C$_{BS}$）通过多相输运模型（AMPT）在 $^{197}$金+$^{197}$金碰撞中研究，能量$\sqrt{s_{NN}}$为200 GeV。 C$_{BS}$的中心度依赖性在模型中呈现出来，从部分子相到强子物质。 我们发现系统在部分子凝聚后仍保留部分预测的 C$_{BS}$特征签名。 但在强子再散射后，这些预测的特征签名完全消失。 因此似乎部分子凝聚的强子化过程和强子再散射都导致了 C$_{BS}$特征签名的消失。 显示英文摘要

摘要： Baryon-strangeness correlation (C$_{BS}$) has been investigated with a multi-phase transport model (AMPT) in $^{197}$Au + $^{197}$Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. The centrality dependence of C$_{BS}$ is presented within the model, from partonic phase to hadronic matter. We find that the system still reserve partial predicted signatures of C$_{BS}$ after parton coalescence. But after hadronic rescattering, the predicted signatures will be obliterated completely. So it seems that both coalescence hadronization process and hadronic rescattering are responsible for the disappearance of the C$_{BS}$ signatures.
