Symmetries on the moduli space of (2,2) superstring vacua

Nuclear Physics B, 1991
Abstract Symmetries of the space of (2,2) string vacua for c = 3, 6, 9 are discussed in the context of orbifoldized Landau-Ginzburg theories. A general method for finding the maximal symmetry groups on the moduli space of untwisted marginal operators is presented, by studying deformations of superpotentials.

Non-Compact Current Algebras and Heterotic Superstring Vacua

, 1990
It has been shown that a four dimensional finite and consistent superstring theory [1] can be constructed by combining any 2-dimensional superconformai field theory with a central charge c=9 with a superstring propagating in flat 4-dimensional Minkowski space-time.

Heterotic superstring vacua in four dimensions based on non-compact affine current algebras

Nuclear Physics B, 1990
Abstract New classes of unitary conformal and superconformal theories based on cosets of affine non-compact current algebras are suggested. Unitarity restrictions and the structure of the modules labelled by the primary states are discussed in general terms as well as in detail for SU (1,1)/ U (1), SU (N,M)/ SU (N) × SU (M) × U (1)

(2, 2) VACUA OF THE HETEROTIC SUPERSTRING COMPACTIFIED ON SU(2)³ GROUPFOLDS

International Journal of Modern Physics A, 1991
In this paper we classify the (2, 2) superstring vacua corresponding to non-linear σ-models on SU (2)3 groupfolds fermionized by 18 + 18 Majorana fermions. For the subclass of the completely bosonizable vacua, the generation number ½X is a multiple of 12 and the number of tangent-bundle deformations End(T) is a multiple of 4.
