GRASS Seminar | Chronicles of Regular Black Holes: The Higher-Curvature Saga

In this talk, I will show how an infinite tower of higher-curvature corrections to Einstein gravity gives rise to the formation of regular black holes in space-time dimensions larger than four. These theories consist of specific combinations of higher-curvature terms at each order, multiplied by free couplings. I will begin by introducing a class of higher-curvature gravities with second-order equations of motion on spherically symmetric backgrounds, which will play a central role in the mechanism leading to these regular black holes. I will then examine the static and spherically symmetric black holes of these theories, which become regular after the introduction of the infinite tower of corrections, and demonstrate that the spherical collapse of a thin shell indeed leads to the formation of such regular black holes.
