晶格上的有限温度QCD--状态2010

Finite Temperature QCD on the Lattice -- Status 2010

Kazuyuki Kanaya

摘要:

近几年来,格点上的有限温度QCD研究取得了很大的进展。采用各种改进的交错夸克作用量对2+1味QCD进行了大尺度动力学模拟,得到了各种热力学量的结果,这些结果可以外推到物理夸克质量附近的连续极限,从而能够与实验直接比较。与此同时,交错型格夸克的理论上的不安促使一些小组加速对威尔逊型夸克和格手征夸克的研究。在这篇综述中,我讨论了有限温度QCD在过去一年中所取得的这些重要进展。

英文摘要:

In the last couple of years, there has been big progress in finite temperature QCD on the lattice. Large-scale dynamical simulations of 2+1 flavor QCD with various improved staggered quark actions have been started to produce results for various thermodynamic quantities which are extrapolated to the continuum limit at around physical quark masses, and thus are capable for a direct comparison with experiment. At the same time, the theoretical uneasiness with staggered-type lattice quarks motivated several groups to accelerate studies with Wilson-type quarks and lattice chiral quarks. In this review, I discuss these important developments in finite temperature QCD made in the past year.
