Duality in Heterotic Vacua With Four Supercharges
نویسنده
چکیده
We study heterotic vacua with four supercharges in three and four space-time dimensions and their duals obtained as M/F-theory compactified on Calabi-Yau fourfolds. We focus on their respective moduli spaces and derive the Kähler potential for heterotic vacua obtained as circle compactifications of four-dimensional N = 1 heterotic theories. The Kähler potential of the dual theory is computed by compactifying 11-dimensional supergravity on Calabi-Yau fourfolds. The duality between these theories is checked for K3-fibred fourfolds and an appropriate F-theory limit is discussed.

D = 6 , N = 1 String Vacua and Duality 1
We review the structure D = 6, N = 1 string vacua with emphasis on the different connections due to T -dualities and S-dualities. The topics discussed include: Anomaly cancellation; K3 and orbifold D = 6, N = 1 heterotic compactifications; T -dualities between E8 × E8 and Spin(32)/Z2 heterotic vacua; non-perturbative heterotic vacua and small instantons; N = 2 TypeII/Heterotic duality in D = 4 ...
متن کاملA Note on Toroidal Compactifications of the Type I Superstring and Other Superstring Vacuum Configurations with 16 Supercharges
We show that various disconnected components of the moduli space of superstring vacua with 16 supercharges admit a rationale in terms of BPS un-orientifolds, i.e. type I toroidal compactifications with constant non-vanishing but quantized vacuum expectation values of the NS×NS antisymmetric tensor. These include various heterotic vacua with reduced rank, known as CHL strings, and their dual typ...
متن کاملDuality Between the Webs of Heterotic and Type II Vacua
We discuss how transitions in the space of heterotic K3×T 2 compactifications are mapped by duality into transitions in the space of Type II compactifications on Calabi–Yau manifolds. We observe that perturbative symmetry restoration, as well as non-perturbative processes such as changes in the number of tensor multiplets, have at least in many cases a simple description in terms of the reflexi...
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...
