夸克偶素晶格研究的新进展

Recent Developments in Lattice Studies for Quarkonia

O. Kaczmarek

摘要:

在讨论了由猝灭QCD中轻夸克关联函数的连续外推结果得到的双轻子率和电导率的结果之后,我将综述夸克-胶子等离子体中夸克偶子的格点量子色动力学研究的最新进展。本文将讨论从强子关联函数的格点量子色动力学计算中提取谱特性的最新进展。除了束缚态的介质修正和它们在等离子体中的解离,我将集中讨论输运系数,如从晶格上不同的关联函数中提取的重夸克扩散常数。目前的局限性和未来的研究夸克偶素和相关的输运系数的晶格将进行讨论。

英文摘要:

After discussing results of dilepton rates and electrical conductivity obtained from continuum extrapolated results of light quark correlation functions in quenched QCD I will give a review on recent developments in lattice QCD studies for quarkonia in the quark gluon plasma. Recent progress in the extraction of spectral properties from lattice QCD calculations of hadronic correlation functions will be discussed. Besides medium modifications of bound states and their dissociation in the plasma I will focus on transport coefficients, like heavy quark diffusion constants extracted from different correlation functions on the lattice. Present limitations and future perspectives for studies of quarkonia and related transport coefficients on the lattice will be discussed.
