N = 1 String Duality
We discuss duality between Type IIA string theory, eleven-dimensional supergravity, and heterotic string theory in four spacetime dimensions with N = 1 supersymmetry. We find theories whose infrared limit is trivial at enhanced symmetry points as well as theories with N = 1 supersymmetry but the field content of N = 4 theories which flow to the N = 4 fixed line in the infrared.
متن کاملD = 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 کاملN=1 Mirror Symmetry and Open/Closed String Duality
We show that the exact N = 1 superpotential of a class of 4d string compactifications is computed by the closed topological string compactified to two dimensions. A relation to the open topological string is used to define a special geometry for N = 1 mirror symmetry. Flat coordinates, an N = 1 mirror map for chiral multiplets and the exact instanton corrected superpotential are obtained from t...
متن کاملBranes and N=1 Duality in String Theory
We propose a construction of dual pairs in four dimensional N=1 supersymmetric Yang-Mills theory using branes in type IIA string theory. Supersymmetric gauge theories invariant under eight or sixteen supercharges (e.g. N=2 and N=4 supersymmetric Yang-Mills theories in four dimensions, respectively) have been intensively studied in the last few years. Many of the diverse strong coupling phenomen...
متن کاملNote on N = 0 string as N = 1 string
A similarity transformation, which brings a particular class of the N = 1 string to the N = 0 one, is explicitly constructed. It enables us to give a simple proof for the argument recently proposed by Berkovits and Vafa. The N = 1 BRST operator is turned into the direct sum of the corresponding N = 0 BRST operator and that for an additional topological sector. As a result, the physical spectrum...
