متن کاملTopological amplitudes in heterotic strings with Wilson lines
We consider d=4, N = 2 compactifications of heterotic strings with an arbitrary number of Wilson lines. In particular, we focus on known chains of candidate heterotic/type II duals. We give closed expressions for the topological amplitudes F (g) in terms of automorphic forms of SO(2 + k, 2,Z), and find agreement with the geometric data of the dual K3 fibrations wherever those are known. a marle...
متن کاملThe Moduli Space and Phase Structure of Heterotic Strings in Two Dimensions
We explore the moduli space of heterotic strings in two dimensions. In doing so, we introduce new lines of compactified theories with Spin(24) gauge symmetry and discuss compactifications with Wilson lines. The phase structure of d = 2 heterotic string theory is examined by classifying the hypersurfaces in moduli space which support massless quanta or discrete states. Finally, we compute the to...
متن کاملLectures on Perturbative String Theories
These lecture notes on String Theory constitute an introductory course designed to acquaint the students with some basic facts of perturbative string theories. They are intended as preparation for the more advanced courses on non-perturbative aspects of string theories in the school. The course consists of five lectures: 1. Bosonic String, 2. Toroidal Compactifications, 3. Superstrings, 4. Hete...
متن کاملToroidal Compactification of Heterotic 6D Non-Critical Strings Down to Four Dimensions
The low-energy limit of the 6D non-critical string theory with N = 1 SUSY and E8 chiral current algebra compactified on T2 is generically an N = 2 U(1) vector multiplet. We study the analog of the Seiberg-Witten solution for the low-energy effective action as a function of E8 Wilson lines on the compactified torus and the complex modulus of that torus. The moduli space includes regions where th...
