چکیده

We present a novel global E7(7) symmetry in five-dimensional maximal supergravity as well as an E8(8) symmetry in d=4. These symmetry groups which are known to be present after reduction to d=4 and d=3, respectively, appear as conformal extensions of the respective well-known hidden-symmetry groups. A global scaling symmetry of the Lagrangian is the key to enhancement of E6(6) to E7(7) in d=5 and E7(7) to E8(8) in d = 4. The group action on the physical fields is induced by conformal transformations in auxiliary spaces M of dimensions 27 and 56, respectively. The construction is analogous to the one where the conformal group of Minkowski space acts on the boundary of AdS5 space. A geometrical picture underlying the action of these “conformal duality groups” is given.

Starting from N = 1 scalar supermultiplets in 2+1 dimensions, we build explicitly the composite superpartners which define a N = 2 superalgebra induced by the initial N = 1 supersymmetry. The occurrence of this extension is linked to the topologically conserved current out of which the composite superpartners are constructed.
