On scattering off the extreme Reissner-Nordström black hole in N=2 supergravity
Takashi Okamura
Abstract
The scattering amplitudes for the perturbed fields of the N=2 supergravity about the extreme Reissner-Nordström black hole is examined. Owing to the fact that the extreme hole is a BPS state of the theory and preserves an unbroken global supersymmetry(N=1), the scattering amplitudes of the component fields should be related to each other. In this paper, we derive the formula of the transformation of the scattering amplitudes.
