SUSY breaking by a metastable ground state : why the early universe preferred the non-supersymmetric vacuum.

Abel, S. A. and Chu, C-S. and Jaeckel, J. and Khoze, V. V. (2007) 'SUSY breaking by a metastable ground state : why the early universe preferred the non-supersymmetric vacuum.', Journal of high energy physics., 1 . p. 89.

Abstract

Supersymmetry breaking in a metastable vacuum is re-examined in a cosmological context. It is shown that thermal effects generically drive the Universe to the metastable minimum even if it begins in the supersymmetry-preserving one. This is a generic feature of the ISS models of metastable supersymmetry breaking due to the fact that SUSY preserving vacua contain fewer light degrees of freedom than the metastable ground state at the origin. These models of metastable SUSY breaking are thus placed on an equal footing with the more usual dynamical SUSY breaking scenarios.
