Black hole discharge in massive electrodynamics and black hole disappearance in massive gravity

TL;DR

This paper investigates how black holes lose charge and mass in theories with massive photons and gravity, revealing a process where black holes can effectively disappear due to field decay.

Contribution

It introduces the concept of discharge modes in massive electrodynamics and extends the idea to massive gravity, proposing a novel black hole disappearance mechanism.

Findings

Discharge mode describes electric field decay in massive electrodynamics.

Black hole mass can effectively decrease in massive gravity.

Black hole disappearance may occur due to field decay processes.

Abstract

We define and calculate the "discharge mode" for a Schwarzschild black hole in massive electrodynamics. For small photon mass, the discharge mode describes the decay of the electric field of a charged star collapsing into a black hole. We argue that a similar "discharge of mass" occurs in massive gravity and leads to a strange process of black hole disappearance.
