On the Worldsheet Formulation of the Six-Dimensional Self-Dual String
arXiv:hep-th/9607190 · doi:10.1016/0370-2693(96)01092-1
Abstract
Despite recent evidence indicating the existence of a new kind of self-dual six-dimensional superstring, no satisfactory worldsheet formulation of such a string has been proposed. In this note we point out that a theory built from Z_4 parafermions may have the right properties to describe the light-cone conformal field theory of this string. This indicates a possible worldsheet formulation of this theory.
