A Description of Schwarzschild Black Holes in terms of Intersecting M-branes and antibranes

TL;DR

This paper models Schwarzschild black holes using intersecting M-branes and antibranes with massless excitations, calculating entropy that closely matches supergravity results, providing a new microscopic perspective.

Contribution

It introduces a novel description of Schwarzschild black holes through intersecting M-branes and antibranes, extending previous brane models to non-charged black holes.

Findings

Entropy calculation matches supergravity results up to a numerical factor.

Provides an empirical interpretation for the entropy discrepancy.

Demonstrates the viability of brane-antibrane configurations for modeling Schwarzschild black holes.

Abstract

Intersecting M-branes are known to describe multi charged black holes. Using a configuration of such intersecting branes and antibranes, together with massless excitations living on them, we give a description of Schwarzschild black holes following Danielsson, Guijosa, and Kruczenski. We calculate the entropy of these black holes and find that it agrees, upto a numerical factor, with the entropy of the corresponding Schwarzschild black holes in supergravity approximation. We give an empirical interpretation of this factor.
