Abstract

I will discuss some work in progress describing scattering dilaton-graviton waves off of thin branes in a three dimensional space-time.
The gravity problem has some novel aspects I have not seen in the general relativity literature before and is reminiscent of the optics problem of scattering light off of a rough, translucent window. The motivation for our study was that the process has a dual holographic realization as scattering in a family of strongly interacting (non-conformal) 1+1 dimensional quantum field theories.
We are struggling with one or two remaining puzzles before releasing the work on the arXiv, and I hope the audience may help us to resolve them.
