Gaugino condensation in an improved heterotic M-theory
@article{Ahmed2008GauginoCI, title={Gaugino condensation in an improved heterotic M-theory}, author={Nasr Ahmed and Ian G. Moss}, journal={Journal of High Energy Physics}, year={2008}, volume={2008}, pages={108-108} }
Gaugino condensation is discussed in the context of a consistent new version of low energy heterotic M-theory. The four dimensional reduction of the theory is described, based on simple boson and fermion backgrounds. This is generalised to include gaugino condenstates and various background fluxes, some with non-trivial topology. It is found that condensate and quantised flux contributions to the four-dimensional superpotential contain no corrections due to the warping of the higher dimensional…
