Eleven-Dimensional Supergravity in Superspace,In the present scenario of our theoretical understanding of fundamental particle interactions, extended supergravity appears to be the only viable gauge quantum field theory which may succeed in the attempts at superunification of electroweak, strong and gravitational interactions.

N = 8 Supergravity,After the trip through superspace in 11 dimensions under the direction of S. Ferrara, . I am supposed to bring you back to ordinary 4 dimensional space-time by presenting to you the N = 8 supergravity, a work done in collaboration with B. Julia..

The On-Shell N=8 Supergravity in Superspace,The N=8 supergravity theory is presented in superspace. Only the physical fields are kept so that the theory is on-shell. The global E7 and local SU(8) invariances arise naturally.

Exceptional Groups for Grand Unification,n some detail. It is demonstrated that in particular the “top model of E.” has a number of advantages over SU(5) and SO(10) models. The spontaneous symmetry breaking of E. via 27 and 351 dimensional Higgs fields can give the correct pattern of vector boson and fermion masses and provides for interesting relations.
