Equivalence of 3D Spinning String and Superstring

Abstract

We perform a light-cone gauge quantization of the Ramond closed spinning string in three spacetime dimensions (3D). The spectrum is Lorentz invariant and identical to that of the 3D Green-Schwarz closed superstring with ${\cal N}=2$ space-time supersymmetry, quantized in light-cone gauge.Comment: 15 pages. Revised to include discussion of modular invarianc
