RHIC处QCD流体的磁性方案

Magnetic Scenario for the QCD Fluid at RHIC

Jinfeng Liao, Edward Shuryak

摘要:

本文介绍了RHIC上QCD流体的“磁方案”的新发展。有限T磁单极的最新晶格数据用于确定夸克-胶子等离子体离子体磁分量的参数:特别是我们展示了磁密度和等离子体耦合$Γ_M$如何随着$T$而变化。然后我们讨论了重离子数据引起的一个中心问题:即$T_c$周围QCD流体中的极短耗散长度。我们表明,洛伦兹捕获效应,目前只有在一个等离子体中的电荷和磁荷和最大的一个相等的50%-50%的混合物,是微观机制,导致近乎完美的流动性。

英文摘要:

We present new developments of the "magnetic scenario" for the QCD Fluid observed at RHIC. The recent lattice data for finite T monopoles are used to pin down the parameters of the magnetic component of quark-gluon plasma: in particular we show how the magnetic density and plasma coupling $Γ_M$ change with $T$. We then discuss one central issue imposed by the heavy ion data: i.e. the extremely short dissipation length in the QCD fluid around $T_c$. We show that the Lorentz trapping effect, present only in a plasma with both electric and magnetic charges and maximal for an equal 50%-50% mixture, is the microscopic mechanism leading to the nearly perfect fluidity.
