Abstract:
The Cartan forms, infinitesimal and finite transformations of the Goldstone and
matter superfields, the generators, torsion, and curvature are calculated for the
nonlinear realization of extended superconformal symmetry. A covariant condition
that eliminates goldstonions of the special superconformal transformations is
discussed, together with a chiral realization. A “minimal” effective action for the
Goldstone fields parametrized by ordinary space-time coordinates is constructed.
