Gaugino Condensation and the Vacuum Expectation Value of the Dilaton
نویسندگان
چکیده
The mechanism of gaugino condensation has emerged as a prime candidate for supersymmetry breakdown in low energy effective supergravity (string) models. One of the open questions in this approach concerns the size of the gauge coupling constant which is dynamically fixed through the vev of the dilaton. We argue that a nontrivial gauge kinetic function f(S) could solve the potential problem of a runaway dilaton. The actual form of f(S) might be constrained by symmetry arguments. ∗ Invited talk at the International Workshop on Supersymmetry and Unification of Fundamental Interactions, SUSY 95, Ecole Polytechnique, Palaiseau, France, May 1519, 1995

Supersymmetry Breaking in Superstring Theory by Gaugino Condensation and its Phenomenology
The weakly-coupled heterotic string is known to have problems of dilaton/moduli stabilization, supersymmetry breaking (by hidden-sector gaugino condensation), gauge coupling unification (or the Newton’s constant), QCD axion, as well as cosmological problems involving dilaton/moduli and axion. We study these problems by adopting the point of view that they arise mostly due to our limited calcula...
متن کاملSupersymmetry Breaking in String Theory * LANCE
I briefly review the problems with previous investigations of supersymmetry breaking in string theory 1 at tree-level, at one-loop, and non-perturbatively. A variant of the original non-perturbative scenario is proposed, in which gaugino condensation takes place in two different strongly-interacting hidden-sector gauge groups. In the new scenario it is possible to generate a large hierarchy of ...
متن کاملNonperturbative corrections to the Kähler potential
We present the results of a detailed investigation into the consequences of adding specific string motivated non-perturbative corrections to the usual tree level Kähler potential in dilaton dominated scenarios. The success of the model is judged through our ability to obtain a realistic vacuum expectation value for the dilaton ^ReS&;2, corresponding to the true minima of the scalar potential an...

This talk summarizes recent investigations 1,2 of the phenomenology of heterotic string-derived supergravity theories invoking gaugino condensation in a hidden sector to break supersymmetry and is a condensation of material more fully presented elsewhere. 1,2,3 The philosophy behind the research reported here is to ask whether we can obtain intuition on the nature of the hidden sector matter an...

We examine the process of formation of the gaugino condensation within a Nambu-Jona-Lasinio type approach. We construct an effective Lagrangian description for the gaugino condensation which include a Weyl compensator superfield whose vacuum expectation value is related to the gaugino condensation.
