The aim of this paper is to study the quantum tunneling process for charged vector particles through the horizons of more generalized black holes by using the Proca equation. For this purpose, we consider a pair of charged accelerating and rotating black holes with Newman–Unti–Tamburino parameter and a black hole in 5D gauged super-gravity theory, respectively. Further, we study the tunneling probability and corresponding Hawking temperature for both black holes by using the WKB approximation. We find that our analysis is independent of the particles species whether or not the background black hole geometries are more generalized.

This study set out to investigate charged vector particles tunneling via horizons of a pair of accelerating rotating charged NUT black holes under the influence of quantum gravity. To this end, we use the modified Proca equation incorporating generalized uncertainty principle. Applying the WKB approximation to the field equation, we obtain a modified tunneling rate and the corresponding corrected Hawking temperature for this black hole. Moreover, we analyze the graphical behavior of the corrected Hawking temperature with respect to the event horizon for the given black hole. By considering quantum gravitational effects on Hawking temperatures, we discuss the stability analysis of this black hole. For a pair of black holes, the temperature increases with the increase in rotation parameters a and , correction parameter , black hole acceleration , and arbitrary parameter k, and decreases with the increase in electric e and magnetic charges g.

In this paper, we have investigated the Hawking radiation process as a semiclassical quantum tunneling phenomenon from black ring and 5D Myers–Perry black holes. Using Lagrangian of Glashow–Weinberg–Salam model with background electromagnetic field (for charged W-bosons) and the Wentzel–Kramers–Brillouin approximation, we have evaluated the tunneling rate or probability of charged vector particles at through the horizons by taking into account the electromagnetic vector potential. Moreover, we have calculated the corresponding Hawking temperature via Boltzmann factor for both types of considered background and analyzed the whole spectrum generally.
