Radius stabilization by constant boundary superpotentials in warped space
摘要
A warped space model with a constant boundary superpotential has been an efficient model both to break supersymmetry and to stabilize the radius, when hypermultiplet, compensator and radion multiplet are taken into account. In such a model of the radius stabilization, the radion and moduli masses, the gravitino mass and the induced soft masses are studied. We find that a lighter physical mode composed of the radion and the moduli can have mass of the order of a TeV and that the gravitino mass can be of the order of 10 GeV. It is also shown that soft mass induced by the anomaly mediation can be of the order of 100GeV and can be dominant compared to that mediated by bulk fields. Localized F terms and D terms are discussed as candidates of cancelling the cosmological constant. We find that there is no flavor changing neutral current problem in a wide range of parameters.
