Eight-dimensional, N=1 supergravity with SU(4/1) hidden supersymmetry

초록

We describe D=8, N=1 supergravity with an SU(4/1) superalgebra which is a supersymmetric version of SO(6)S U(1). Possible supermultiplets agree with typical representations of SU(4/1). Furthermore U(1) supercharges are automatically determined by just demanding that the representation is real. Dimensional reductions to the D=7, N=2 and D=6, N=2 theories are described by using branching rules of SU(4/1). © 1990 The American Physical Society.
