About

We examine vacuum structures of effective theories of moduli fields in the frameworks of Type IIB and F-theory flux compactifications. For two explicit examples, we numerically investigate the distributions of a huge number of local minima of the effective potential in the complex structure and dilaton directions in moduli fields. Interestingly, our results for the distributions of non-supersymmetric minima exhibit that larger string coupling generically leads to smaller vacuum energy/cosmological constant..
