Primordial Black Holes Are True Vacuum Nurseries
Louis Hamaide, Lucien Heurtier, Shi-Qian Hu +1
The Hawking evaporation of primordial black holes (PBH) reheats the Universe locally, forming hot spots that survive throughout their lifetime. We propose to use the temperature pr…
Exact Schwinger Proper Time Renormalisation
Steven Abel, Lucien Heurtier
We derive an exact version of the Schwinger Proper Time Renormalisation Group flow equation from first principles from the complete path integral, without using any perturbative ex…
Stasis, Stasis, Triple Stasis
Keith R. Dienes, Lucien Heurtier, Fei Huang +2
Many theories of BSM physics predict the existence of large or infinite towers of decaying states. In a previous paper (arXiv:2111.04753) we pointed out that this can give rise to…
Hunting for Neutral Leptons with Ultra-High-Energy Cosmic Rays
Robert Heighton, Lucien Heurtier, Michael Spannowsky
Next-generation large-volume detectors, such as GRAND, POEMMA, Trinity, TAROGE-M, TAMBO, or PUEO, have been designed to search for ultra-high-energy cosmic rays (UHECRs) with unpre…
Primordial Black Hole Archaeology with Gravitational Waves from Cosmic Strings
Anish Ghoshal, Yann Gouttenoire, Lucien Heurtier +1
Light primordial black holes (PBHs) with masses smaller than g () evaporate before the onset of Big-Bang nucleosynthesis, rendering their detection rather…
