Philippe Brax, Gautam Mandal, Yaron Oz
TL;DR
This paper constructs supergravity solutions for coincident brane-antibrane systems, analyzes their properties, and explores their connection to non-supersymmetric black holes and tachyon condensation.
Contribution
It introduces a new supergravity framework for describing non-BPS branes and their interpolation to black hole solutions, advancing understanding of non-supersymmetric configurations.
Findings
Supergravity solutions for N Dp-branes and ar{N} ar{Dp}-branes are constructed.
An interpolation between brane-antibrane solutions and Schwarzschild black holes is developed.
The study provides insights into tachyon condensation and non-supersymmetric black hole physics.
Abstract
We construct supergravity solutions that correspond to N Dp-branes coinciding with \bar{N} \bar{Dp}-branes. We study the physical properties of the solutions and analyse the supergravity description of tachyon condensation. We construct an interpolation between the brane-antibrane solution and the Schwarzschild solution and discuss its possible application to the study of non-supersymmetric black holes.
