Contribution of bouncing gravitons to the energy-momentum tensor
Abstract
In a model of 3-brane with matter embedded in 5D space-time conditions for gravitons emitted from the brane to the bulk to return back to the brane are found. A method to calculate contribution to the energy-momentum tensor from multiple bouncing gravitons is developed. Contribution to the energy momentum tensor from gravitons of the first bounce is calculated. The result is much smaller than those obtained previously.
