Primordial Black Hole Hot Spots and Out-of-Equilibrium Dynamics
Jacob Gunn, Lucien Heurtier, Yuber F. Perez-Gonzalez +1
When light primordial black holes (PBHs) evaporate in the early Universe, they locally reheat the surrounding plasma, creating hot spots with temperatures that can be significantly…
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…
Dark matter and observable Lepton Flavour Violation
Lucien Heurtier, Daniele Teresi
Seesaw models with leptonic symmetries allow right-handed (RH) neutrino masses at the electroweak scale, or even lower, at the same time having large Yukawa couplings with the Stan…
Generating X-ray lines from annihilating dark matter
Emilian Dudas, Lucien Heurtier, Yann Mambrini
We propose different scenarios where a keV dark matter annihilates to produce a monochromatic signal. The process is generated through the exchange of a light scalar of mass of ord…
