Stasis in an Expanding Universe: A Recipe for Stable Mixed-Component Cosmological Eras
Keith R. Dienes, Lucien Heurtier, Fei Huang +3
One signature of an expanding universe is the time-variation of the cosmological abundances of its different components. For example, a radiation-dominated universe inevitably give…
Primordial Black Hole Evaporation and Dark Matter Production: II. Interplay with the Freeze-In/Out Mechanism
Andrew Cheek, Lucien Heurtier, Yuber F. Perez-Gonzalez +1
We study how the evaporation of primordial black holes (PBHs) can affect the production of dark matter (DM) particles through thermal processes. We consider fermionic DM interactin…
Primordial Black Hole Evaporation and Dark Matter Production: I. Solely Hawking radiation
Andrew Cheek, Lucien Heurtier, Yuber F. Perez-Gonzalez +1
Hawking evaporation of black holes in the early Universe is expected to copiously produce all kinds of particles, regardless of their charges under the Standard Model gauge group.…
Resurrecting Low-Mass Axion Dark Matter Via a Dynamical QCD Scale
Lucien Heurtier, Fei Huang, Tim M. P. Tait
In the framework where the strong coupling is dynamical, the QCD sector may confine at a much higher temperature than it would in the Standard Model, and the temperature-dependent…
