Metastable supersymmetry breaking in a cooling universe
Abstract
We look at the recently proposed idea that susy breaking can be accomplished in a metastable vacuum. In the context of one of the simplest models (the Seibergdual of superQCD), we address the following question: if we look at this theory as it cools from high temperature, is it at all possible that we can end up in a susybreaking metastable vacuum? To get an idea about the answer, we look at the free energy of the system at high temperature. We conclude that the phasestructure of the freeenergy as the temperature drops, is indeed such that there is a second order phase transition in the direction of the nonsusy vacuum at a finite T = T_{c}^{Q}. On the other hand, the potential barrier in the direction of the susy vacuum is there all the way till T ~ 0.
