Abstract
A scenario for stabilization of axionic moduli fields in the context of type IIB Calabi-Yau flux compactifications is discussed in detail. We consider the case of a Calabi-Yau orientifold with h1,1−≠0 which allows for the presence of B2 and C2-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 α'-corrections to the Kähler 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.
