有限密度下的QCD

QCD at finite density

Sourendu Gupta

摘要:

本文综述了有限密度下QCD的研究进展。我首先讨论了一些新的算法,已被应用到其他理论与符号问题。然后,我讨论了在QCD中使用级数展开的解析延拓方法,并回顾了使用这种方法得到的一些结果。到目前为止,有几个不同的模拟使用的方法,并在一起,他们给出了系统的晶格效应的估计,这原来是可控的。最后,我讨论了直接比较这些晶格预测与新的实验数据,结果在一个非常愉快的协议。

英文摘要:

Developments in QCD at finite density are reviewed. I begin by discussing some new algorithms which have been applied to other theories with sign problems. Then I discuss the method of analytic continuation in QCD using a series expansion and review some of the results obtained using this method. By now there are several different simulations using the method, and together they give estimates of the systematic lattice effects, which turn out to be controlled. Finally I discuss a direct comparison of some of these lattice predictions with new experimental data which results in a very pleasant agreement.
