TL;DR

This paper proposes a D3-brane–anti-D3-brane system at low temperature to model the absorption and probabilistic emission of a minimal scalar field by an extremal type IIB supergravity threebrane black hole. Using this framework, the authors demonstrate that the system reproduces low-frequency absorption and long-distance emission, providing strong evidence for the brane-antibrane model and confirming energy consistency between the two component gases, while correcting and extending prior results on near-extremal threebrane absorption probabilities.

ABSTRACT

Se demuestra que un modelo propuesto anteriormente sobre la base de un sistema deD3-branas-anti-D3-branas a temperatura baja que puede reproducirla absorcion de baja frecuencia y las emisiones probabilisticas de la threebrane negro de la super gravedad tipo IIB extremadamente lejos, por arbitrarias ondas parcial es de un campo escalar minimo. Nuestros calculos se refieren, en particular al caso de la threebrane neutral, que corresponde al agujero negro de Schwarzschild en siete dimensiones, dichos resultados no solo proporcionan evidencia significativa a favor del modelo de brana-antibrana, sino que tambien fundamenta la condicion de las energias de los dos gases componentes que se muestran de acuerdo entre si. En resumen, se ha propuesto corregirlos resultados anteriores, sobre la probabilidad de absorcion de la threebrane en situacion casi extrema, y extenderla a la maxima distancia

Motivation & Objective

• To investigate whether a low-temperature D3-brane–anti-D3-brane system can reproduce the low-frequency absorption and long-distance emission of a minimal scalar field by an extremal type IIB supergravity threebrane black hole.
• To provide evidence supporting the validity of the brane-antibrane model in describing black hole thermodynamic and scattering properties.
• To verify the consistency of energy levels between the two component gases in the brane-antibrane system.
• To correct and extend previous results on the absorption probability of a threebrane in a near-extremal configuration to maximal distances.

Proposed method

• The study employs a low-temperature D3-brane–anti-D3-brane system as a dual description of the extremal threebrane black hole in type IIB supergravity.
• The model is used to compute the absorption cross-section of a minimal scalar field at low frequencies.
• Emission probabilities are calculated for the scalar field at arbitrarily large distances from the black hole.
• The analysis focuses on the neutral threebrane case, corresponding to a seven-dimensional Schwarzschild black hole.
• The framework is applied to test consistency between the energy levels of the two component gases in the brane-antibrane system.
• Theoretical results are compared with prior findings to identify discrepancies and extend the validity of absorption probability calculations.

Experimental results

Research questions

• RQ1 Can a D3-brane–anti-D3-brane system at low temperature accurately reproduce the low-frequency absorption of a minimal scalar field by an extremal threebrane black hole?
• RQ2 Does the brane-antibrane model correctly describe the long-distance emission of scalar radiation from the threebrane black hole?
• RQ3 Are the energy levels of the two component gases in the brane-antibrane system consistent with each other in this dual description?
• RQ4 How do the absorption probabilities in the near-extremal regime compare with previous theoretical estimates, especially at maximal distances?

Key findings
