GEOMETRIZATION OF PLANCK LENGTH IN COMPOSITE GRAVITY AND SUPERGRAVITY

The Volkov-Akulov (VA) standard action can be treated as composite cosmological term, with composite vierbein described by massless Goldstone fermions. By considering massive Goldstone fermions one can relate classically VA and composite Einstein gravity actions, provided the mass of Goldstone fermions, Planck mass and the SSB scale are related. It is also shown that the action of N=1 and N=2 supergravity with composite gauge fields can be written respectively modulo topological terms as N=1 and N=2 composite supersymmetric cosmological terms.
