Dual String Pairs With N = 1 and N = 2 Supersymmetry in Four Dimensions

چکیده
Based on a simple adiabatic argument and by considering the heterotic string counterpart of certain symmetries of Type II superstrings such as (−1) F L and orientation reversal, we construct orbifold candidates for dual pairs of heterotic and Type II string theories with N = 2 and N = 1 supersymmetry. We also analyze from a similar point of view the K3 fibrations that enter in recently proposed N = 2 candidates and use this structure together with certain orientation-reversing symmetries to construct N = 1 dual pairs. These pairs

Dual Pairs of Type II String Compactification
Using a U -duality symmetry of type II compactification on T 4 represented by triality action on the T -duality group, and applying the adiabatic argument we construct dual pairs of type II compactifications in lower dimensions. The simplicity of this construction makes it an ideal set up for testing various conjectures about string dualities. In some of these models the type II string has a pe...
متن کاملString Vacua with N = 2 Supersymmetry in Four Dimensions
In this article we review four-dimensional string vacua with N = 2 space-time supersymmetry. In particular, we will discuss several aspects of the string-string duality between the heterotic string, compactified on K3 × T 2 , and the type II superstring compactified on a Calabi-Yau threefold. We investigate the massless supersymmetric spectra, showing agreement for a large class of dual heterot...
متن کاملNon - perturbative corrections in N = 2 strings †
We investigate the non-perturbative equivalence of some heterotic/type IIA dual pairs with N = 2 supersymmetry. We compute R-like corrections, both on the type IIA and on the heterotic side. The coincidence of their perturbative part provides a test of duality. The type IIA result is then used to predict the full, non-perturbative correction to the heterotic effective action. We determine the i...

متن کامل2 v 1 3 0 Se p 19 97 1 N = 1 Dual String Pairs and their Modular Superpotentials
We review the duality between heterotic and F–theory string vacua with N = 1 space-time supersymmetry in eight, six and four dimensions. In particular, we discuss two chains of four-dimensional F–theory/heterotic dual string pairs, where F–theory is compactified on certain elliptic Calabi-Yau fourfolds, and the dual heterotic vacua are given by compactifications on elliptic Calabi-Yau threefold...
