论文摘要
长期以来，在高能重型离子碰撞中产生的重夸克通过Quark-Gluon等离子体（QGP）的扩散已被认为是其运输特性的出色探测。此外，实验观察到的重味的哈德子提供了有关运输夸克的强发化过程的宝贵信息。在这里，我们回顾了QGP中夸克相互作用的理论发展的最新进展，以及它们与非扰动强调过程的关系，并讨论了RHIC和LHC重型离子碰撞中相关现象学的最新状态。在QGP中，重夸克的相互作用也构成了重型夸克尼亚的描述，它也控制其运输参数。因此，我们将重点介绍旨在统一描述介质中开放和隐藏的重量颗粒颗粒的理论方法，并讨论如何通过晶格QCD“数据”来限制它们，并用于推断显微镜相互作用的基本特性以及强烈燃料QGP的强度相互作用的基本特性。
The diffusion of heavy quarks through the quark-gluon plasma (QGP) as produced in high-energy heavy-ion collisions has long been recognized as an excellent probe of its transport properties. In addition, the experimentally observed heavy-flavor hadrons carry valuable information about the hadronization process of the transported quarks. Here we review recent progress in the theoretical developments of heavy-quark interactions in the QGP and how they relate to the nonperturbative hadronization process, and discuss the recent status of the pertinent phenomenology in heavy-ion collisions at the RHIC and the LHC. The interactions of heavy quarks in the QGP also constitute a central building block in the description of the heavy quarkonia which controls their transport parameters as well. We will thus focus on theoretical approaches that aim for a unified description of open and hidden heavy-flavor particles in medium, and discuss how they can be constrained by lattice QCD "data" and utilized to deduce fundamental properties of the microscopic interactions and emerging spectral properties of the strongly coupled QGP.
