Destabilizing the gaugino condensate in modular invariant supergravity

چکیده
We investigate the stability of the hidden sector gaugino condensate in a SL(2,Z)-invariant supergravity model inspired by the E8⊗E8 heterotic string, using the chiral superfield formalism. We calculate the Plancksuppressed corrections to the “truncated approximation” for the condensate value and the scalar potential. A transition to a phase with zero condensate occurs near special points in moduli space and at large compactification radius. We discuss the implications for the T-modulus dependence of supersymmetry-breaking.

متن کاملGaugino Masses in Modular Invariant Supergravity
We calculate gaugino masses in string-derived models with hidden-sector gaugino condensation. The linear multiplet formulation for the dilaton superfield is used to implement perturbative modular invariance. The contribution arising from quantum effects in the observable sector includes the term recently found in generic supergravity models. A much larger contribution is present if matter field...
متن کاملAnisotropic Solutions For Orbifold Moduli From Duality Invariant Gaugino Condensates
The values of the T and U moduli are studied for those Z N Coxeter orbifolds with the property that some of the twisted sectors have fixed planes for which the six-torus T 6 can not be decomposed into a direct sum T 2 T 4 with the fixed plane lying in T 2. Such moduli in general transform under a subgroup of the modular group SL(2, Z). The moduli are determined by minimizing the effective poten...
متن کاملGaugino Condensation , S - Duality and Supersymmetry Breaking in Supergravity Models
The status of the gaugino condensation as the source of supersymmetry breaking is reexamined. It is argued that one cannot have stable minima with broken supersymmetry in models where the dilaton is coupled only linearly to the gaugino condensate. We show that the problems of the gaugino condensate mechanism can be solved by considering nonstandard gauge kinetic functions, created by nonperturb...
متن کاملOn Inflation in the Presence of a Gaugino Condensate
We study the effect of inflation on gaugino condensation in supergravity. Unless the Hubble scale H is significantly below the gaugino condensation scale, the gaugino condensate is a dynamical variable which cannot be integrated out. For a sufficiently high H, the gaugino condensate evolves to zero which in turn leads to dilaton/moduli destabilization. In practice, this often occurs at the Hubb...
