Sumit R. Das, Gary Gibbons, Samir D. Mathur
TL;DR
This paper calculates the low energy absorption cross-sections for scalars and spin-1/2 particles into spherically symmetric black holes across various dimensions, revealing their relation to the black hole's area.
Contribution
It provides a general formula for absorption cross-sections for different particles in arbitrary-dimensional black hole spacetimes.
Findings
Scalar cross section equals the black hole area.
Spin-1/2 particle cross section relates to a conformally flat spatial metric.
Results apply to black holes in arbitrary dimensions.
Abstract
In this paper we compute the low energy absorption cross-section for minimally coupled massles scalars and spin- particles, into a general spherically symmetric black hole in arbitrary dimensions. The scalars have a cross section equal to the area of the black hole, while the spin- particles give the area measured in a flat spatial metric conformally related to the true metric.
