Gravitational scattering in the ADD model revisited

Author

  • Malin Sjödahl

Summary, in English

It is argued that the assumption that the standard model particles live on a finite brane in the ADD model does in itself imply a finite propagator for virtual Kaluza-Klein mode exchange. The part of the propagator relevant for large distance scattering is cut-off-independent for scattering at distances large compared to the brane width. The matrix element corresponding to this part can also, at least for an odd number of extra dimensions, be Fourier transformed to position space, giving back the extra-dimensional version of Newton's law. For an even number of extra dimensions a corresponding result is found by requiring that Newton's law should be recovered.
