Dilaton Supersymmetry Breaking
We argue that dilaton supersymmetry breaking in string derived supergravity requires an effective superpotential which is not separable as a function of the dilaton times a function of the moduli. We show that in a simple model with hidden sector matter condensation and a dilaton independent term one can easily obtain |FS| 6 = 0. For a wide range of realistic model parameters |FS| >> |FT | and ...
متن کاملPhenomenological Implications of Supersymmetry Breaking by the Dilaton
We investigate the low energy properties of string vacua with spontaneously broken N = 1 supersymmetry by a dilaton F -term. As a consequence of the universal couplings of the dilaton, the supersymmetric mass spectrum is determined in terms of only three independent parameters and more constrained than in the minimal supersymmetric Standard Model. For a μ-term induced by the Kähler potential th...
متن کاملDilaton Stabilization in the Context of Dynamical Supersymmetry Breaking through
We study gaugino condensation in the context of superstring effective theories using the linear multiplet formulation for the dilaton superfield. Including nonperturbative corrections to the Kähler potential for the dilaton may naturally achieve dilaton stabilization, with supersymmetry breaking and gaugino condensation; these three issues are interrelated in a very simple way. In a toy model w...
متن کاملComposite supersymmetric axion-dilaton-dilatino system and the breaking of supersymmetry.
The spontaneous breakdown of the scale, the chiral and the superconformal symmetries for a hidden SU (N) gauge group is studied in an effective lagrangean approach. The relevant low-energy degrees of freedom are taken to be the composite Goldstone particles associated with these three broken symmetries. Super-symmetry is spontaneously broken in the large N limit and soft breaking terms in the o...
متن کاملDual Supersymmetry Algebras from Partial Supersymmetry Breaking
The partial breaking of supersymmetry in flat space can be accomplished using any one of three dual representations for the massive N = 1 spin-3/2 multiplet. Each of the representations can be “unHiggsed”, which gives rise to a set of dual N = 2 supergravities and supersymmetry algebras.
