nLab super 2-brane in 4d

Idea

By the brane scan there exists a classical (pre-quantum) Green-Schwarz super p-brane sigma model for $p =2$ (supermembrane) with target space being $d = 4$ dimensional super Minkowski spacetime with N=1 supersymmetry, or more generally a superspacetime which is a super Cartan geometry solving the equations of motion of d=4 N=1 supergravity. (The literature traditionally knows this as the “4d supermembrane”.)

Its double dimensional reduction is the super 1-brane in 3d (see there) for $N=(1,1)$ 3d supergravity.

The Brane molecule

Furthermore, there exists a more general classification of possible supermembranes in spacetime with $S$ spatial dimensions and $T$ time dimensions, appearing in (Blencowe-Duff 88). In this sense, the brane scan is but the $T=1$ branch of the brane molecule. The objects appearing here are expected to be related to other generalizations of string theory. See D=12 supergravity and bosonic M-theory.
