Abstract	We present a representation of supersymmetry from which gauge theories coupled with matter can be constructed from a single superconnection. As an illustration, we consider three and four spacetime dimensions and appropriate supergroups. All the fields, gravity, gauge and matter, enter as parts of the connection, that transforms in the adjoint representation of the gauge group and, in principle, there is no need for superpartners. The model has a built in Weyl scale invariance. A mass gap between bosons and fermions may be created by the breaking of Weyl scale symmetry induced by gravity or by a chiral symmetry or supersymmetry breaking induced by the fermion condensate. In three spacetime dimensions a mass gap is created without breaking susy and in four dimensions the theory contains the Nambu--Jona-Lasinio term for chiral symmetry breaking.
