About Interaction of the Spinor and Scalar Fields, Removing Contribution of the Scalar Field in the Geometry of the Space-Time

Cover Page

Abstract


In the static cylindrically symmetric metric and cosmological metric Bianchi I we consider the interacting scalar and spinor fields with the Lagrangian of the interaction Lint = V (φ)S2, where V (φ) is arbitrary function of scalar field φ, S = ψ¯ψ is an invariant of the spinor field ψ. We obtain exact solutions of the Einstein, spinor and scalar equations and one exhibited that function V (φ) is absent in the components of the energy-momentum tensor for the interacting fields. It means that the considered type of the interaction removes the contribution of the scalar field in the geometry of the space-time.
