# Festina lente:1 EFT constraints from charged black hole evaporation in de Sitter

@article{Montero2019FestinaLE, title={Festina lente:1 EFT constraints from charged black hole evaporation in de Sitter}, author={Miguel Montero and Thomas Van Riet and G. Venken}, journal={arXiv: High Energy Physics - Theory}, year={2019} }

In the Swampland philosophy of constraining EFTs from black hole mechanics we study charged black hole evaporation in de Sitter space. We establish how the black hole mass and charge change over time due to both Hawking radiation and Schwinger pair production as a function of the masses and charges of the elementary particles in the theory. We find a lower bound on the mass of charged particles by demanding that large charged black holes evaporate back to empty de Sitter space, in accordance… Expand
