Spinor brane

The thick brane model supported by a nonlinear spinor field is constructed. The different cases with the various values of the cosmological constant $Λ(< = >) 0$ are investigated. It is shown that regular analytical spinor thick brane solutions with asymptotically Minkowski (at $Λ=0$) or anti-de Sitter spacetimes (at $Λ<0$) do exist.
