G-Fluxes and Non-Perturbative Stabilisation of Heterotic M-Theory
We examine heterotic M-theory with a parallel M5 brane. After deriving the four-dimensional low-energy supergravity potential including open membrane instantons, gaugino condensation and M5 brane instantons, we focus on the first two non-perturbative effects. We find in the pure open membrane case, where the parallel M5 gets stabilized at the middle of the orbifold interval, that the vacuum ene...
متن کاملNon-Perturbative Superpotential from Membrane Instantons in Heterotic M-Theory
A formalism for calculating the open supermembrane contribution to the non-perturbative superpotential of moduli in heterotic M-theory is presented. This is explicitly applied to the Calabi-Yau (1, 1)-moduli and the separation modulus of the end-of-the-world BPS threebranes, whose non-perturbative superpotential is computed. The role of gauge bundles on the boundaries of the open supermembranes...
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 کاملHeterotic Fluxes and Non-Kähler Geometries
In connecting ten (or eleven) dimensional string theory to our low-energy four dimensional observable world, a standard geometrical approach is to wrap the extra dimensions around an internal compact manifold X6. The four dimensional physical observables are then determined by the characteristics of X6. For many years, X6 was commonly taken to be a Calabi-Yau (CY) manifold, mainly because a CY ...
متن کاملDiscrete Torsion in Perturbative Heterotic String Theory
In this paper we analyze discrete torsion in perturbative heterotic string theory. In previous work we have given a purely mathematical explanation of discrete torsion as the choice of orbifold group action on a B field, in the case that dH = 0; in this paper we perform the analogous calculations in heterotic strings where dH = 0.
