  4. Abstract:
  5. We consider the emission of charged scalar particles from a Schwarzschild black hole. It is shown that these particles can interact with each other through pair annihilation and, as a result, produce photons. These photons make a correction to the spectrum of photons that are directly emitted from the black hole. By solving the field equations using the Wentzel-Kramers-Brillouin approximation, the pair annihilation rate is taken into account for the most probable case, i.e. the first order, and therefore the correction will be of the order of e2. Considering this scenario, we show that most interactions take place near the event horizon of the black hole, yet the number of interactions is not large enough to make a noticeable modification in the radiation spectrum of particles. © 2022 The Author(s).
