ABSTRACT: Moduli stabilization in the type IIA massive string theory so far was achieved
only in the AdS vacua. The uplifting to dS vacua has not been performed as yet: neither
the analogs of type IIB anti-D3 brane at the tip of the conifold, nor the appropriate D-terms
have been identified. The hope was recently expressed that the F-term uplifting may work.
We investigate this possibility in the context of a simplified version of the type IIA model
developed in hep-th/0505160 and find that the F-term does not uplift the AdS vacua to
dS vacua with positive CC. Thus it remains a challenging task to find phenomenologically
acceptable vacua in the type IIA string theory.
