Warped Compactifications on Calabi-Yau Fourfolds
Abstract:- Motivated by phenomenological applications we consider (warped)
compactifications of type IIA string theory on Calabi-Yau fourfolds in
the presence of Ramond-Ramond fluxes. The main goal of the talk is a
description of low-energy physics, including a new superspace formulation
of two-dimensional N = (2,2) dilaton supergravity coupled to
matter, and computation of the effective superpotentials induced by
fluxes.
