Hawking Radiation of Vector Particles via Tunneling From 4-Dimensional And 5-Dimensional Black Holes

TL;DR

This paper investigates Hawking radiation of vector particles from 4D and 5D black holes using the Proca equation and WKB approximation, revealing dependencies on spacetime properties and consistency with scalar and fermion tunneling results.

Contribution

It extends Hawking radiation analysis to vector particles in higher-dimensional black holes using the Proca equation and confirms results align with scalar and fermion tunneling.

Findings

Tunneling rates depend on spacetime properties like horizon, mass, and angular momentum.

Hawking temperatures match those obtained from scalar and fermion tunneling.

Results apply to both 4D Kerr-de Sitter and 5D Schwarzschild-Tangherlini black holes.

Abstract

Using Proca equation and WKB approximation, we investigate Hawking radiation of vector particles via tunneling from 4-dimensional Kerr-de Sitter black hole and 5-dimensional Schwarzschild-Tangherlini black hole. The results show that the tunneling rates and Hawking temperatures are depended on the properties of spacetime (event horizon, mass and angular momentum). Besides, our results are the same as scalars and fermions tunneling from 4-dimensional Kerr-de Sitter black hole and 5-dimensional Schwarzschild-Tangherlini black hole.
