有限温度SU(N)规范理论的奇异相

Exotic phases of finite temperature SU(N) gauge theories

Joyce C. Myers, Michael C. Ogilvie

摘要:

通过最小化单圈有效势,计算了含重费米子的SU(N)规范理论的高温相图。考虑费米子在伴随(Adj)表示在不同的N,我们观察到各种相位时,Nf >= 2马约拉纳风味和周期性边界条件施加到费米子。此外,受限相是微扰可达的。当N = 3时,我们将具有反周期边界条件的基本(F)表象费米子加到伴随QCD中,以显示Z(3)对称性如何在受限相中破缺。

英文摘要:

We calculate the phase diagrams at high temperature of SU(N) gauge theories with massive fermions by minimizing the one-loop effective potential. Considering fermions in the adjoint (Adj) representation at various N we observe a variety of phases when Nf >= 2 Majorana flavours and periodic boundary conditions are applied to fermions. Also the confined phase is perturbatively accessible. For N = 3, we add Fundamental (F) representation fermions with antiperiodic boundary conditions to adjoint QCD to show how the Z(3)-symmetry breaks in the confined phase.
