Moduli Stabilization in Heterotic M-theory
نویسندگان
چکیده
We examine the stabilization of the two typical moduli, the length ρ of the eleventh segment and the volume V of the internal six manifold, in compactified heterotic M -theory. It is shown that, under certain conditions, the phenomenologically favored vacuum expectation values of ρ and V can be obtained by the combined effects of multi-gaugino condensations on the hidden wall and the membrane instantons wrapping the three cycle of the internal six manifold.

Moduli Stabilization in Meta-Stable Heterotic Supergravity Vacua
We revisit the issue of moduli stabilization in a class of N = 1 four dimensional supergravity theories which are low energy descriptions of standard perturbative heterotic string vacua compactified on Calabi–Yau spaces. In particular, we show how it is possible to stabilize the universal dilaton and Kähler moduli in a de Sitter/Minkowski vacuum with low energy supersymmetry breaking by means o...
متن کاملPerturbative Antibrane Potentials in Heterotic M Theory
We derive the perturbative four-dimensional effective theory describing heterotic M theory with branes and antibranes in the bulk space. The backreaction of both the branes and antibranes is explicitly included. To first order in the heterotic εS expansion, we find that the forces on branes and antibranes vanish and that the Kachru-Kallosh-Linde-Trivedi (KKLT) procedure of simply adding to the ...
متن کاملModuli Stabilization in the Heterotic/IIB Discretuum
We consider supersymmetric compactifications of type IIB and weakly coupled heterotic string-theory in the presence of G resp. H-flux and various nonperturbative effects. We point out that non-perturbative effects change the Hodge structure of the allowed fluxes in type IIB significantly. In the heterotic case it is known that, in contrast to the potential read off from dimensional reduction, t...
متن کاملVacuum Stability in Heterotic M-Theory
The problem of the stabilization of moduli is discussed within the context of compactified strongly coupled heterotic string theory. It is shown that all geometric, vector bundle and five-brane moduli are completely fixed, within a phenomenologically acceptable range, by non-perturbative physics. This result requires, in addition to the full space of moduli, non-vanishing Neveu-Schwarz flux, ga...
متن کاملOn Open Membranes, Cosmic Strings and Moduli Stabilization
We discuss how cosmic strings can be created in heterotic M-theory compactifications with stable moduli. We conclude that the only appropriate candidates seem to be fundamental open membranes with a small length. In four dimensions they will appear as strings with a small tension. We make an observation that, in the presence of the vector bundle moduli, it might be possible to stabilize a five-...
