Theory of supersymmetric fermions and gravielectromagnetism

On the basis of nonlinear realization of the supersymmetric algebra in the 5-dimensional world a 5-dimensional Riemannian manifold is built whose metric is parametrized by the components of Dirac bispinor. Using the scalar curvature of this manifold as a Lagrangian of the bispinor field, a theory of the supersymmetric neutrino of the 5-dimensional world is built. It is shown that from the viewpoint of the 4-dimensional world, this theory describes in a unified manner the fermions and their own gravielectromagnetic field
