论文摘要
在高能量核碰撞中，重型标记的喷气机是研究Quark-Gluon等离子体（QGP）的特性的有用的硬探针。在本次演讲中，我们介绍了$ d^0 $ d^0 $ Meson radial分布相对于P+P和PB+PB碰撞的$ 5.02 $ TEV中的Jet轴的第一个理论预测，它与可用的实验数据显示了一个不错的协议。研究中的中等射流演化是由蒙特卡洛传输模型描述的，该模型已与初始事件合并为近临界订单（NLO）加Parton Shower（PS）事件发生器Sherpa提供的输入。在这样的进化过程中，考虑了热和密集培养基中的弹性和非弹性Parton能量损失。在相同的模拟框架内，我们预测了PB+PB碰撞中的魅力和底部夸克的径向曲线的不同修改模式：喷射淬灭效果将导致Charm Quarks扩散到落后半径，而导致底部夸克底部夸克分布在靠近喷气轴的位置。
In high energy nuclear collisions, heavy flavor tagged jets are useful hard probes to study the properties of the quark-gluon plasma (QGP). In this talk, we present the first theoretical prediction of the $D^0$ meson radial distributions in jets relative to the jet axis both in p+p and Pb+Pb collisions at $5.02$ TeV, it shows a nice agreement with the available experimental data. The in-medium jet evolution in the study is described by a Monte Carlo transport model which has been incorporated with the initial events as input provided by the next-to-leading order (NLO) plus parton shower (PS) event generator SHERPA. In such evolution process, both elastic and inelastic parton energy loss in the hot and dense medium are taken into account. Within this same simulation framework, we predict different modification patterns of the radial profile of charm and bottom quarks in jets in Pb+Pb collisions: jet quenching effect will lead the charm quarks diffuse to lager radius while lead the bottom quarks distributed closer to jet axis.
