Couplings of gravitational currents with Chern-Simons gravities    [PDF]

Ümit Ertem, Özgür Açık

Coupling of conserved p-brane currents with non-abelian gauge theories is done consistently by using Chern-Simons forms. Conserved currents localized on p-branes that have gravitational origin can be constructed from Killing-Yano forms of underlying spacetime. We propose a generalization of the coupling procedure with Chern-Simons gravities to the gravitational conserved currents case. In odd dimensions, the field equations of coupled Chern-Simons gravities which describe the local curvature on p-branes are obtained. In special cases of three and five dimensions, the field equations are investigated in detail.
