Cern-th.6213/91 Geometry and Quantum Symmetries of Superstring Vacua
We report on some recent progress which has been made in the understanding of general features of superstring compacti cations. The following aspects are discussed: special geometry of the moduli space of (2,2) vacua, target-space duality symmetries, di erential equations for the periods of holomorphic three-forms, and higher loop (genus) string corrections to the tree-level e ective action thr...
متن کاملCosmological Implications of Domain Walls due to Duality Invariant Moduli Sector of Superstring Vacua
We study cosmological implications of the duality (PSL(2,Z)) invariant potential for the compactification radius T , arising in a class of superstring vacua. We show that in spite of having only one minimum in the fundamental domain of the T field there are two types of non-supersymmetric domain walls: one is associated with the discrete Peccei-Quinn symmetry T → T + i, analogous to the axionic...
متن کاملEnhanced Symmetries in Multiparameter Flux Vacua
We give a construction of type IIB flux vacua with discrete R-symmetries and vanishing superpotential for hypersurfaces in weighted projective space with any number of moduli. We find that the existence of such vacua for a given space depends on properties of the modular group, and for Fermat models can be determined solely by the weights of the projective space. The periods of the geometry do ...
متن کاملFlux Vacua and Branes of the Minimal Superstring
We analyze exactly the simplest minimal superstring theory, using its dual matrix model. Its target space is one dimensional (the Liouville direction), and the background fields include a linear dilaton, a possible tachyon condensate, and RR flux. The theory has both charged and neutral branes, and these exhibit new and surprising phenomena. The smooth moduli space of charged branes has differe...
متن کاملA cosmological constant from degenerate vacua
Under the hypothesis that the cosmological constant vanishes in the true ground state with lowest possible energy density, we argue that the observed small but finite vacuum-like energy density can be explained if we consider a theory with two or more degenerate perturbative vacua, which are unstable due to quantum tunneling, and if we still live in one of such states. An example is given makin...
