“…In the framework of N ¼ 2 supersymmetric gauge theory, some supersymmetry breaking models with Uð1Þ R symmetry breaking were considered [22][23][24][25][26]. It would be interesting to study effects of the finite temperature in those models (see also [27]). In this section, we consider series expansions of the thermal functions at high temperature.…”

We investigate finite temperature effects in O'Raifeartaigh models with global symmetries which exhibit supersymmetry breaking at a metastable vacuum accompanied by Uð1Þ 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 Uð1Þ 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.

“…The key issue to realize the U(1) R-symmetry breaking is that the model should include multi-flavors with a peculiar choice of different U(1) R-charges [11]. The generalized O'Raifeartaigh models with finite temperatures have been studied to investigate thermal history of supersymmetry breaking vacua in the early universe [12,13,14,15,16,17,18,19]. Effects of finite temperature and a chemical potential to the U(1) R-symmetry breaking have been studied for a supersymmetric model with a single flavor [20] 1 , where the chemical potential breaks the U(1) R-symmetry even at high temperatures.…”

We investigate thermal one-loop effective potentials in multi-flavor models with chemical potentials. We study four-dimensional models in which each flavor has different global U (1) charges. Accordingly they have different chemical potentials. We call these "nonuniform chemical potentials," which are organized into a diagonal matrixμ. The mass matrix at a vacuum does not commute withμ. We find that the effective potential is divided into three parts. The first part is the Coleman-Weinberg potential. The UV divergence resides only in this part. The second is the correction to the Coleman-Weinberg potential that is independent of temperature, and the third depends on both temperature andμ. Our result is a generalization of the thermal potentials in previous studies for models with single and multi-flavors with (uniform) chemical potentials and reproduces all the known results correctly.

Supersymmetry andR-symmetry breaking in metastable vacua at finite temperature and density

We study a meta-stable supersymmetry-breaking vacuum in a generalized O'Raifeartaigh model at finite temperature and chemical potentials. Fields in the generalized O'Raifeartaigh model possess different R-charges to realize R-symmetry breaking. Accordingly, at finite density and temperature, the chemical potentials have to be introduced in a non-uniform way. Based on the formulation elaborated in our previous work we study the one-loop thermal effective potential including the chemical potentials in the generalized O'Raifeartaigh model. We perform a numerical analysis and find that the Rsymmetry breaking vacua, which exist at zero temperature and zero chemical potential, are destabilized for some parameter regions. In addition, we find that there are parameter regions where new R-symmetry breaking vacua are realized even at high temperature by the finite density effects.
