宇宙学QCD相变的AdS/CFT方面
AdS/CFT aspects of the cosmological QCD phase transition
摘要:
近年来,对AdS/CFT对应的研究使人们对QCD有了更深的认识。新的结果包括夸克-胶子等离子体的性质和禁闭/解除禁闭相变,这两个都是非常重要的情况下的QCD相变在早期宇宙。本文研究了这些新结果对基于微扰QCD、格点量子色动力学和MIT袋模型的宇宙学QCD相变计算的影响。
英文摘要:
Recently, deeper understanding of QCD emerges from the study of the AdS/CFT correspondence. New results include the properties of quark-gluon plasma and the confinement/deconfinement phase transition, which are both very important for the scenario of the QCD phase transition in the early universe. In this paper, we study some aspects of how the new results may affect the old calculations of the cosmological QCD phase transition, which are mainly based on the studies of perturbative QCD, lattice QCD and the MIT bag model.
