论文摘要
重型夸克是在相对论重离子碰撞的最早阶段生产的，它探测了碰撞中产生的夸克 - 杜伦等离子体的整个历史。最初，血浆中有染色体动力场，可以被视为经典。我们使用Fokker-Planck方程来研究重型夸克在这样的系统中的运输，该系统称为Glasma，其中夸克与长波长的染色体动力场相互作用。我们计算用于计算传输方程的碰撞项的场相关器。最后，研究了glasma中重夸克的能量损失和动量扩大。这两个量都是相当大的，并且在很大程度上取决于。
Heavy quarks, which are produced at the earliest stage of relativistic heavy-ion collisions, probe the entire history of the quark-gluon plasma that is created in the collision. Initially the plasma is populated with chromodynamic fields which can be treated as classical. We study the transport of heavy quarks across such a system, which is called glasma, using a Fokker-Planck equation where the quarks interact with long wavelength chromodynamic fields. We compute field correlators which are used to calculate the collision terms of the transport equation. Finally, the energy loss and momentum broadening of heavy quarks in the glasma are studied. Both of these quantities are sizable and strongly directionally dependent.
