Stringy corrections to the Kahler potential, SUSY breaking and the stabilization of (all) Kahler moduli
Abstract:
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 spacetimes, when the alpha' corrections
to the Kahler potential are combined with a single contribution to the
non-perturbative superpotential by an ample divisor.
