HET Seminar | Stringy Corrections to the Kahler Potential, SUSY Breaking and the Stabilization of (All) Kahler Moduli

Speaker: Per Berglund (University of New Hampshire)

We revisit the idea that stringy corrections to the Kahler potential in N=1 flux compactifications to four dimensions can qualitatively change the structure of the effective scalar potential even at large volume. Following recent work by Bobkov et al [arXiv:1003.1982], we find that there exist non-supersymmetric vacua, including metastable de Sitter space times, when the alpha' corrections to the Kahler potential are combined with a single contribution to the non-perturbative super potential by an ample divisor.
