N=4 superconformal symmetry for the covariant quantum superstring [rapid communication]
Abstract
We extend our formulation of the covariant quantum superstring as a WZNW model with N = 2 superconformal symmetry to N = 4. The two anticommuting BRST charges in the N = 4 multiplet of charges are the usual BRST charge Q_{S} and a charge Q_{V} proposed by Dijkgraaf, Verlinde and Verlinde for topological models. Using our recent work on "gauging cosets", we then construct a further charge Q_{C} which anticommutes with Q_{C} +Q_{V} and which is intended for the definition of the physical spectrum.
