Finite temperature behaviour of the ISS-uplifted KKLT model

Understand

We study the static phase structure of the ISS-KKLT model for moduli stabilisation and uplifting to a zero cosmological constant.

• Since the supersymmetry breaking sector and the moduli sector are only gravitationally coupled, we expect negligible quantum effects of the modulus upon the ISS sector, and the other way around.
• Under this assumption, we show that the ISS fields end up in the metastable vacua.
• The reason is not only that it is thermally favoured (second order phase transition) compared to the phase transition towards the supersymmetric vacua, but rather that the metastable vacua form before the supersymmetric ones.
