Journal ArticleDOI
N=1 supergravity theories with gravitational mass scales.
Burt A. Ovrut,Stuart Raby +1 more
TL;DR: The octet and triplet superfields substantially reduce the prediction for m/sub t/, making a light top quark more natural, and the breaking can be driven by arbitrarily small values of the top-quark mass m/ sub t/.
Journal ArticleDOI
Symmetric Vacua in Heterotic M-Theory
Andre Lukas,Burt A. Ovrut +1 more
TL;DR: In this paper, the authors analyzed symmetric vacua of heterotic M-theory on smooth Calabi-Yau three-folds and showed that such vacua do not exist for elliptically fibered Calabi Yau spaces.
Journal ArticleDOI
Domain walls, percolation theory, and Abell clusters.
Zygmunt Lalak,Burt A. Ovrut +1 more
TL;DR: This work considers theories with late-time phase transitions that lead to the formation of energetically soft domain wall effects and calculates the spatial properties and distribution using percolation theory to accurately predict the richness distribution of Abell clusters.
Journal ArticleDOI
A supersymmetric left-right confining model of the weak interactions
Yee Jack Ng,Burt A. Ovrut +1 more
TL;DR: In this article, the supersymmetric theory of weak interactions is extended to a left-right symmetric model, which can accommodate at most three generations of quarks and leptons.
Book ChapterDOI
Covariant Harmonic Supergraphity for N = 2 Super Yang--Mills Theories
TL;DR: In this article, the background field method for general N = 2 super Yang-Mills theories formulated in the n = 2 harmonic superspace is reviewed and the covariant harmonic supergraph technique is applied to rigorously prove the N=2 non-renormalization theorem.
