TL;DR
This paper compares non-relativistic Newtonian scattering with black-hole scattering, revealing similar behaviors in gray-body factors and their relation to quantum gravity and conformal field theory.
Contribution
It demonstrates that black-hole gray-body factors mirror Newtonian scattering amplitudes in the weak-field limit, independent of supersymmetry, and explores their connection to conformal field theory.
Findings
Gray-body factors have the same functional form in black-hole and Newtonian scattering.
Black-hole scattering amplitudes approach Newtonian results in the weak-field limit.
The behavior is independent of supersymmetry and linked to conformal field theory.
Abstract
We discuss non-relativistic scattering by a Newtonian potential. We show that the gray-body factors associated with scattering by a black hole exhibit the same functional dependence as scattering amplitudes in the Newtonian limit, which should be the weak-field limit of any quantum theory of gravity. This behavior arises independently of the presence of supersymmetry. The connection to two-dimensional conformal field theory is also discussed.
