KÄHLER SIGMA MODELS FROM SUPERSYMMETRIC GAUGE THEORIES

Abstract

The geometrical structure of the noncompact, nonhomogeneous Kähler sigma models arising from supersymmetric gauge theories is described. Topics discussed include the choice of target manifold for the sigma model, the supersymmetric vacuum alignment problem and the nature of chiral symmetry breaking, the role of isometry anomalies, the construction of the Kähler potential and metric, and the embedding of the conventional compact coset space sigma model in the supersymmetric Kähler model.
