THE 10-DIMENSIONAL GREEN-SCHWARZ SUPERSTRING IS A TWISTED NEVEU-SCHWARZ-RAMOND STRING

An action for the ten-dimensional Green-Schwarz superstring with N = 2 world-sheet superconformal invariance has recently been quantized and used to calculate superstring scattering amplitudes. In this paper, i t is shown that the N = 2 stress-energy tensor for this Green-Schwarz action can be constructed out of the stress-energy tensor and ghosts o f the Neveu-Schwarz-Ramond action by the standard twisting procedure. In other words, a field redefinition is found from the GS matter field s into the NSR matter and ghost fields which transforms the matter par t of the two fermionic GS superconformal generators into the b ghost a nd shifted BRST current of the NSR string. In light-cone gauge, this f ield redefinition reduces to the usual one relating the light-cone GS and NSR fields.
