Experimentally testing asymptotically safe quantum gravity with
photon-photon scattering [PDF]
Astrid EichhornMatter-quantum gravity interactions can be used for direct and also indirect experimental tests of quantum gravity. We focus on photon-photon scattering in asymptotically safe gravity as a direct test of the small-scale structure of spacetime, and discuss how near-future experiments can probe asymptotic safety in a setting with large extra dimensions.View original: http://arxiv.org/abs/1210.1528
