super 2-brane in 4d



String theory




By the brane scan there exists a classical (pre-quantum) Green-Schwarz super p-brane sigma model for p=2p =2 (supermembrane) with target space being d=4d = 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)N=(1,1) 3d supergravity.
