Latetime correlators in semiclassical particleblackhole scattering
Abstract
We analyze the quantum corrected geometry and radiation in the scattering of extremal black holes by lowenergy neutral matter. We point out the fact that the correlators of local observables inside the horizon are the same as those of the vacuum. Outside the horizon the correlators at late times are much bigger than those of the (thermal) case obtained neglecting the back reaction. This suggests that the corrected Hawking radiation could be compatible with unitarity.
