Gravitational trapping potential with arbitrary extra dimensions

We extend a recently discovered, nonsingular 6-dimensional brane, solution to D = 4 + n dimensions. As with the previous 6D solution the present solution provides a gravitational trapping mechanism for fields of spin 0, 1 2 , 1, and 2. There is an important distinction between two extra dimensions and n extra dimensions that makes this more than a trivial extension. In contrast to gravity in n > 2 dimensions, gravity in n = 2 dimensions is conformally flat. The stress-energy tensor required by this solution has reasonable physically properties, and for n = 2 and n = 3 can be made to asymptotically go to zero as one moves away from the brane. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review D American Physical Society (APS)
