Grey-body factors of higher dimensional regular black holes in quasi-topological theories
arXiv:2601.22340 · doi:10.1088/1475-7516/2026/05/043
Abstract
We study grey body factors and Hawking radiation of higher dimensional regular black holes arising in quasi topological gravity. These spacetimes incorporate infinite curvature corrections that remove the central singularity while preserving an event horizon and a well defined semiclassical description. We show that, for all considered regular black hole models, the transmission of radiation and the corresponding Hawking evaporation are systematically suppressed compared to the singular black hole solutions of General Relativity.
