Mass and Spin of Exact Solutions of the Poincare Gauge Theory

Abstract

We calculate the mass and spin of exact solutions of the Poincare gauge theory, which asymptotically go over to a de Sitter space of constant curvature. Using certain energy-momentum and spin complexes in suitable frames, we find that the total mass of a spherically symmetric solution is just equal to the mass parameter of the solution, whereas the total spin vanishes.
