热Yang-Mills理论的中心对称降维
Center-symmetric dimensional reduction of hot Yang-Mills theory
摘要:
在高温SU(N)Yang-Mills理论的传统降维有效理论(EQCD)中引入中心对称性,将大大扩展EQCD对解禁闭跃迁的适用性。这种中心对称的有效理论的建设的情况下,两种颜色的审查和晶格模拟结果。模拟结果表明,与EQCD不同,新的中心对称理论经历了与完整理论完全相似的二阶限制相变。
英文摘要:
It is expected that incorporating the center symmetry in the conventional dimensionally reduced effective theory for high-temperature SU(N) Yang-Mills theory, EQCD, will considerably extend its applicability towards the deconfinement transition. The construction of such a center-symmetric effective theory for the case of two colors is reviewed and lattice simulation results are presented. The simulations demonstrate that unlike EQCD, the new center-symmetric theory undergoes a second order confining phase transition in complete analogy with the full theory.
