Title

Spin-3/2 fields in D-dimensional Reissner-Nordstrom black hole spacetimes
Coauthors Chen, Chun-Hung; Cornell, Alan S.; Harmsen, Gerhard E.; Ngcobo, Xolane

Abstract

We study spin-3/2 fields in higher dimensional spherically symmetric black holes. The analysis of these fields in curved spacetimes is usually carried out using the Newman-Penrose formalism. Here we develop a more direct approach using eigenspinor-vectors on spheres, to separate out the angular parts of the fields in the Rarita-Schwinger equation. Moreover, for non Ricci-flat spacetimes, the covariant derivative has to be modified to the supercovariant derivative to maintain gauge invariance. In doing so we obtain the radial equations of the corresponding gauge-invariant variable, from which we evaluate the quasinormal spectra as well as the absorption probabilities using the WKB approximation and the asymptotic iteration method.
