Duality-invariant superstring actions.
Worldsheet supersymmetric string action is written in duality invariant form for flat as well as curved backgrounds. First the action in flat backgrounds is written by introducing auxiliary fields. We also give the superfield form of these actions and obtain the off-shell supersymmetry algebra. The action has a modified Lorentz invariance and supersymmetry and reduces to the usual form when the...
متن کاملDuality Invariant Effective String Actions and Minimal Superstring Unification
Some results are presented concerning duality invariant effective string actions and the construction of automorphic functions for general (2,2) string compactifications. These considerations are applied in order to discuss the minimal unification of gauge coupling constants in orbifold compactifications with special emphasis on string threshold corrections. Talk presented at the Joint Internat...
متن کاملDuality Symmetric Quantization of Superstring
A general covariant quantization of superparticle, Green-Schwarz superstring and a supermembrane with manifest supersymmetry and duality symmetry is proposed. This quantization provides a natural quantum mechanical description of curved BPStype backgrounds related to the ultra-short supersymmetry multiplets. Half-size commuting and anticommuting Killing spinors admitted by such backgrounds in q...
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 کاملDuality Symmetries in N = 2 Heterotic Superstring
We review the derivation and the basic properties of the perturbative prepotential in N=2 compactifications of the heterotic superstring. We discuss the structure of the perturbative monodromy group and the embedding of rigidly supersymmetric monodromies associated with enhanced gauge groups, at both perturbative and non-perturbative level.
