摘要
A scenario for stabilization of axionic moduli fields in the context of type 1113 Calabi-Yau flux compactifications is discussed in detail. We consider the case of a Calabi-Yau orientifold with h_(1,1) not equal 0 which allows for the presence of B-2 and C-2-moduli. In an attempt to generalize the KKLT and the Large Volume Scenario, we show that these axions can also be stabilized - some already at tree level, and others when we include perturbative alpha'-corrections to the Kahler potential K and nonperturbative D3-instanton contributions to the superpotential W. At last, we comment on the possible influence of worldsheet instantons on the process of moduli stabilization.
