Radiation of Charged Particles by Charged Black Hole

TL;DR

This paper analyzes the probability of charged particle emission from charged black holes, focusing on how particle energy influences radiation, and identifies conditions where this mechanism surpasses Hawking radiation.

Contribution

It provides a detailed calculation of particle production probabilities in different energy regimes and delineates parameter ranges where this radiation mechanism dominates.

Findings

Particle production probability varies with particle energy.

The mechanism can dominate over Hawking radiation under certain black hole parameters.

The study covers nonrelativistic and ultrarelativistic limits.

Abstract

The probability of a charged particle production by the electric field of a charged black hole depends essentially on the particle energy. This probability is found in the nonrelativistic and ultrarelativistic limits. The range of values for the mass and charge of a black hole is indicated where the discussed mechanism of radiation is dominating over the Hawking one.
