AbstraktAbstract
We investigate finite temperature effects in O'Raifeartaigh models with global symmetries which exhibit supersymmetry breaking at a metastable vacuum accompanied by U(1)R breaking. 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 allows U(1)R breaking 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.
