Dark matter from mediator decay in early matter domination
Rouzbeh Allahverdi, Ngo Phuc Duc Loc, Jacek K. Osiński
We study dark matter production from mediator decays in scenarios with an epoch of early matter domination. Particles that mediate interactions between dark matter and the standard…
Phenomenology of superheavy decaying dark matter from string theory
Rouzbeh Allahverdi, Chiara Arina, Marco Chianese +4
We study the phenomenology of superheavy decaying dark matter with mass around GeV which can arise in the low-energy limit of string compactifications. Generic features o…
Extending preferred axion models via heavy-quark induced early matter domination
Andrew Cheek, Jacek K. Osiński, Leszek Roszkowski
We examine the cosmological consequences of the heavy quarks in KSVZ-type axion models. We find that their presence often causes an early matter domination phase, altering the evol…
Revisiting signatures of thermal axions in nonstandard cosmologies
Paola Arias, Nicolás Bernal, Jacek K. Osiński +2
We revisit the formation of a thermal population of hadronic axions in nonstandard cosmologies, in light of the recent developments in obtaining continuous and smooth interaction r…
