Nava Gaddam<\/strong> (Utrecht)<\/p>\n\n\n\n Title<\/strong>: The black hole eikonal and the information paradox<\/p>\n\n\n\n Abstract<\/strong>: In this talk, I will show that there is a remarkable phase of quantum gravity (which we will call the ‘black hole eikonal’ phase) where gravitational collision energies near the horizon satisfy E >> \\gamma M_Pl, with \\gamma = M_Pl\/M_BH. I will argue that this regime captures gravitational scattering with impact parameters smaller than the Schwarzschild radius. Scattering amplitudes are unitary suggesting a resolution of the information paradox; I will sketch the explicit derivation of the 2-2 amplitude for massless scalars, non-perturbatively in \\gamma. Owing to the low energies of collisions, there are no firewalls experienced by infalling observers. A consequence of these results is that the information paradox is an emergent one at low energies and does not require detailed ultra-violet physics for a resolution. <\/p>\n\n\n\n Meeting information: You can watch the recording at On February 11 we will have a seminar by Nava Gaddam (Utrecht) Title: The black hole eikonal and the information paradox Abstract: In this talk, I will show that there is a remarkable phase of quantum gravity (which we will call the ‘black hole eikonal’ phase) where gravitational collision energies near the horizon satisfy E … Continue reading “Seminar February 11: N.
