Supersymmetry breaking in M - theory and gaugino condensation
We argue that supersymmetry breaking by gaugino condensation in the strongly coupled heterotic string can be described by an analogue of Scherk–Schwarz com-pactification on the eleventh dimension in M-theory. The M-theory scale is identified with the gauge coupling unification mass, whereas the radius of the eleventh dimension ρ is at an intermediate scale ρ −1 ∼ 10 12 GeV. At the lowest order,...
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 کاملGaugino Condensation, Duality and Supersymmetry Breaking
The status of gaugino condensation in low-energy string theory is reviewed. Emphasis is given to the determination of the efective action below condensation scale in terms of the 2PI and Wilson actions. We illustrate how the different perturbative duality symmetries survive this simple nonperturbative phenomenon, providing evidence for the believe that these are exact nonperturbative symmetries...

We derive the explicit form, and discuss some properties of the moduli dependent effective potential arising from M-theory compactified on M 4 × X × S 1 /Z 2 , when one of the boundaries supports a strongly interacting gauge sector and induces gaugino condensation. We discuss the relation between the explicit gaugino condensate and effective superpotential formulations and find interesting diff...
متن کاملGaugino Condensation in M–theory on S
In the low energy limit of for M–theory on S1/Z2, we calculate the gaugino condensate potential in four dimensions using the background solutions due to Hořava. We show that this potential is free of delta–function singularities and has the same form as the potential in the weakly coupled heterotic string. A general flux quantization rule for the three–form field of M–theory on S1/Z2 is given a...
