Twistor formulation of the nonheterotic superstring with manifest world sheet supersymmetry
1993
Physical Review D, Particles and fields
We propose a new formulation of the D=3 type II superstring which is manifestly invariant under both target-space N=2 supersymmetry and worldsheet N=(1,1) super reparametrizations. This gives rise to a set of twistor (commuting spinor) variables, which provide a solution to the two Virasoro constraints. The worldsheet supergravity fields are shown to play the rôle of auxiliary fields.
