Spin matrices for gravitons and the Humblet decomposition of the angular momentum of gravitational radiation in the linearized theory

摘要: We develop spin matrices for a classical gravitational field in the linearized theory which satisfy angular-momentum commutation relations and are appropriate angular momentum of two. The same come out decomposition density into orbital parts, similar to that carried by Humblet electromagnetic field. To achieve this decomposition, we use obtained from Landau-Lifshitz pseudo-tensor weak gravity limit. note formal connection between momenta fields using Kaluza-Klein idea.
