$v_{2}$的轻重味物理机制及AMPT的质量有序化

The physics mechanisms of light and heavy flavor $v_{2}$ and mass ordering in AMPT

Hanlin Li, Zi-Wei Lin, Fuqiang Wang

摘要:

多相输运(AMPT)模型可以很好地描述重离子碰撞中粒子谱和椭圆各向异性($v_{2}$)的体特性等实验数据。最近的研究表明,AMPT描述的$v_{2}$的数据在小系统的冲突,以及。在这些论文中,我们首先研究了重离子碰撞和小系统碰撞中已识别强子$v_{2}$质量有序的起源。然后,我们根据轻夸克$v_{2}$的逃逸机制研究了粲$v_{2}$的产生机制。

英文摘要:

A Multi-Phase Transport (AMPT) model has been shown to describe experimental data well, such as the bulk properties of particle spectra and elliptic anisotropy ($v_{2}$) in heavy ion collisions. Recent studies have shown that AMPT describes the $v_{2}$ data in small system collisions as well. In these proceedings, we first investigate the origin of the mass ordering of identified hadrons $v_{2}$ in heavy ion as well as small system collisions. We then study the production mechanism of the charm $v_{2}$ in light of the escape mechanism for the light quark $v_{2}$.
