Black hole evaporation in Conformal (Weyl) gravity

Understand

In this work, we explore all possible scenarios in the evaporation process of a spherical neutral AdS black hole in four-dimensional conformal gravity, where the equations of states are branched.

• In one branch, the final states correspond to the extremal black hole where the total decay time is divergent given any initial mass.
• In the other branch, the black holes always evaporate completely with in a finite time; the total decay time depends linearly on the AdS radius, when the mass is taken to be infinity.
