Heterotic coset models and (0, 2) string vacua
Abstract
A Lagrangian definition of a large family of (0, 2) supersymmetric conformal field theories may be made by an appropriate gauge invariant combination of a gauged WessZuminoWitten model, rightmoving supersymmetry fermions, and leftmoving current algebra fermions. Throughout this paper, use is made of the interplay between field theoretic and algebraic techniques (together with supersymmetry) which is facilitated by such a definition. These heterotic coset models are thus studied in some detail, with particular attention paid to the (0, 2) analogue of the N = 2 minimal models, which coincide with the 'monopole'' theory of Giddings, Polchinski and Strominger. A family of modular invariant partition functions for these (0 2) minimal models is presented. Some examples of N = 1 supersymmeric four dimensional string theories with gauge groups E _{6} × G∼ and SO(10) × G∼ are presented, using these minimal models as building blocks. The factor G represents various enhanced symmetry groups made up of products of SU(2) and U(1).
