摘要
Following Ref. 10, we explore the parameter space of the case when the supersymmetry (SUSY) breaking scale is lower, for example, in gauge mediated SUSY breaking model. During inflation, the form of the potential is V 0 plus MSSM a (or A-term b ) inflation. We show that the model works for a wide range of the potential V 0 with the soft SUSY breaking mass m ∼ O(1) TeV. The implication to MSSM (or A-term) inflation is that the flat directions which is lifted by the non-renormalizable terms described by the superpotential W=λ p φ p-1 /M P p-3 with p = 4 and p = 5 are also suitable to be an inflaton field for λ p = O(1) provided there is an additional false vacuum term V 0 with appropriate magnitude. The flat directions correspond to p = 6 also works for 0 ≲ V 0 / M P 4 ≲ 10 -40 . © 2010 World Scientific Publishing Company.
