TL;DR

This paper investigates the quantum tunneling process of charged massive vector particles from charged rotating black strings, deriving the tunneling rate and Hawking temperature using semi-classical methods, and confirming consistency with unitarity.

Contribution

It applies the WKB and Hamilton-Jacobi methods to charged rotating black strings to derive tunneling rates and Hawking temperatures, extending previous analyses to these specific black string configurations.

Findings

Tunneling rate deviates from pure thermality.

Hawking temperature is successfully recovered.

Results are consistent with an underlying unitary theory.

Abstract

We study the quantum tunneling of charged massive vector bosons from a charged static and a rotating black string. We apply the standard methods, first we use the WKB approximation and the Hamilton-Jacobi equation, and then we end up with a set of four linear equations. Finally, solving for the radial part by using the determinant of the metric equals zero, the corresponding tunneling rate and the Hawking temperature is recovered in both cases. The tunneling rate deviates from pure thermality and is consistent with an underlying unitary theory.
