Scalar and vector gauges unification in de Sitter ambient space formalism

We consider the massless minimally coupled scalar field in de Sitter ambient space formalism as a gauge potential or connection field. construct theory by helping an arbitrary constant five-vector $B^\alpha$ analogous to standard theory. The Lagrangian density of interaction between and spinor fields is presented this framework. Yukawa can be extracted from at null curvature limit appropriate choice It shown that permits us unify vector fields. By choosing matrix form for $B^\alpha$, unification spectral action noncommutative geometry rewritten. discuss if considered conformal sector background metric field, it may interpreted different hyperboloids quantum classical point view.
