Idea

The superstring 2-dimensional sigma-model is the analog of the string σ-model but with local worldsheet supersymmetry.

This is the higher dimensional analog of how the superparticle is related to the ordinary relativistic particle.

There are several different incarnations of the superstring.

The relationship between the NRS spinning string and the Green-Schwarz superstring sigma-models is discussed in

This involves the relation between the octonion algebra an spinors in 2+8 dimensions (see also division algebra and supersymmetry):
