多相输运模型中相对论性重离子碰撞中的三粒子关联

Three-particle correlations in relativistic heavy ion collisions in a multiphase transport model

Yifeng Sun, Che Ming Ko

摘要:

利用多相输运模型,考虑可观测的$C_{m,n,m+n}=\langle\negmedspace\langle \cos(mϕ_1+nϕ_2-(m+n)ϕ_3)\rangle\negmedspace\rangle$,研究了相对论重离子碰撞中三粒子混合谐波关联,其中$ϕ_{1,2,3}$为三重态粒子的方位角.我们发现,除了$C_{123}$外,在$\sqrt{s}=$ 200 GeV的Au+Au碰撞中,我们对$C_{112}$,$C_{224}$和$C_{235}$的中心度依赖性以及$C_{123}$和$C_{224}$的相对赝快度依赖性的研究结果与STAR合作组的实验数据符合得相当好.我们讨论了我们的结果的影响。

英文摘要:

Using a multiphase transport model, we study three-particle mixed harmonic correlations in relativistic heavy ion collisions by considering the observable $C_{m,n,m+n}=\langle\negmedspace\langle \cos(mϕ_1+nϕ_2-(m+n)ϕ_3)\rangle\negmedspace\rangle$, where $ϕ_{1,2,3}$ are azimuthal angles of all particle triplets. We find that except for $C_{123}$, our results on the centrality dependence of $C_{112}$, $C_{224}$ and $C_{235}$ as well as the relative pseudorapidity dependence of $C_{123}$ and $C_{224}$ in Au+Au collisions at $\sqrt{s}=$200 GeV agree reasonable well with the experimental data from the STAR Collaboration. We discuss the implications of our results.
