本文研究了具有整体对称性的O 'Raifeartaigh模型中的有限温度效应，该模型在亚稳真空中表现出超对称破缺并伴有破缺。在一定的耦合参数范围内，赝模场在零温下稳定在单圈阶。我们分析的参数空间的行为，根据非零温度，并发现允许breaking的参数区域是相当大的扩展，在足够低的温度，即使它收缩在高温下的预期。我们还讨论了亚稳超对称破缺真空的热历史。
We investigate finite temperature effects in O’Raifeartaigh models with global symmetries which exhibit supersymmetry breaking at a metastable vacuum accompanied bybreaking. The pseudomoduli field is stabilized at one-loop order at zero temperature within some coupling parameter region. We analyze the behavior of the parameter space according to nonzero temperatures and find that the parameter region which allowsbreaking is considerably extended at sufficiently low temperature, even though it shrinks down at high temperature as expected. We also discuss the thermal history of the metastable supersymmetry breaking vacuum.
