Extension of the Penrose representation and its use to describe supersymmetric models
Volkov D. V. , Zheltukhin A. A.
An extension of the Penrose representation is proposed [Eq. (4) ]. It is shown through the use of this extension that massless superparticles (superstrings) and spin particles (fermion strings) in 4-space can be described in a common fashion in terms of commuting Weyl spinors ÉÌ(Ô)(ÉÁá( τ,σ)) and Grassmann Weyl spinors θΑ{τ){θΑ( τ,σ)), which are free of the constraints generated by local (super) symmetries.
