A D=4 N=1 Orbifold of Type I Strings
M. Berkooz, R. G. Leigh
We consider the propagation of Type I open superstrings on orbifolds with four non-compact dimensions and supersymmetry. In this paper, we concentrate on a non-trivial Z_2xZ_…
Anomalies, D-flatness and Small Instantons
R. G. Leigh
Recently, Witten has proposed a mechanism for symmetry enhancement in heterotic string theory, where the singularity obtained by shrinking an instanton to zero size is res…
Duality of Sp(2N) and SO(N) Supersymmetric Gauge Theories with Adjoint Matter
R. G. Leigh, M. J. Strassler
We discuss electric-magnetic duality in two new classes of supersymmetric Yang-Mills theories. The models have gauge group $Sp(2\nc)$ or $SO(\nc)$ with matter in both the adjoint a…
Exact Superpotentials in Four Dimensions
K. Intriligator, R. G. Leigh, N. Seiberg
Supersymmetric gauge theories in four dimensions can display interesting non-perturbative phenomena. Although the superpotential dynamically generated by these phenomena can be hig…
