Energy-momentum complexes for a stringy black hole geometry in a low-energy effective string theory

Abstract

The energy and momentum distributions for a four-dimensional, magnetically charged, stringy black hole geometry, in a low-energy effective string theory, are calculated. To this purpose, the energy-momentum complexes of Einstein, Landau-Lifshitz, Weinberg and Møller are applied. It is found that, in all four prescriptions, the momentum distribution vanishes, while the energies obtained differ, but all are functions of the mass, the scalar charge, and the boost parameter. © 2009 World Scientific Publishing Company.
