| ABSTRACT: |
We study the next-to-minimal supersymmetric standard model. We consider soft supersymmetry breaking parameters, which are induced by the mirage mediation mechanism. We concentrate on the mirage mediation, where the so-called mirage scale is the TeV scale. In this scenario, we can realize the up-type Higgs soft mass of O(200) GeV, while other masses like gaugino and stop masses are heavy such as 1 TeV. Cancellation between the effective mu-term and the down-type Higgs soft mass ameliorates the fine-tuning in the electroweak symmetry breaking. The lightest Higgs mass can be 115-130 GeV. The higgsino and singlino are light and their linear combination is the lightest superparticle. |
