A Review of Three-Family Grand Unified String Models

Zurab Kakushadze, Gary Shiu, S. -H. Henry Tye +1

We review the construction and classification of three-family grand unified models within the framework of asymmetric orbifolds in perturbative heterotic superstring. We give a det…

Duality in Superstring Compactifications with Magnetic Field Backgrounds

I. Antoniadis, E. Gava, K. S. Narain +1

Motivated by the work of Polchinski and Strominger on type IIA theory, where the effect of non-trivial field strengths for p-form potentials on a Calabi-Yau space was discussed, we…

A Remark on Dilaton Stabilization

Gia Dvali, Zurab Kakushadze

Dilaton stabilization may occur in a theory based on a single asymptotically free gauge group with matter due to an interplay between quantum modification of the moduli space and t…

Three-Family Grand Unification in String Theory

Zurab Kakushadze

We briefly discuss the status of three-family grand unified string models.

Calculable e^{-1/λ} Effects

I. Antoniadis, B. Pioline, T. R. Taylor

We identify and evaluate a class of physical amplitudes in four-dimensional N=4 superstring theory, which receive, in the weak coupling limit, contributions of order e^{-1/λ}, wher…

Lectures on Heterotic-Type I Duality

I. Antoniadis, H. Partouche, T. R. Taylor

We present a review of heterotic-type I string duality. In particular, we discuss the effective field theory of six- and four-dimensional compactifications with N>1 supersymmetries…
