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…
Toward a search for axion-like particles at the LNLS
L. Angel, P. Arias, C. O. Dib +8
Axion-Like Particles (ALPs) appear in several dark sector studies. They have gained increasing attention from the theoretical and experimental community. In this work, we propose t…
Dark Matter Axions in the Early Universe with a Period of Increasing Temperature
Paola Arias, Nicolás Bernal, Jacek K. Osiński +1
We consider the production of axion dark matter through the misalignment mechanism in the context of a nonstandard cosmological history involving early matter domination by a scala…
Vortex solutions in the presence of Dark Portals
Paola Arias, Ariel Arza, Fidel A. Schaposnik +2
The existence of hidden sectors weakly coupled to the visible one has been extensively studied as a way to extend the Standard Model (SM) and to provide a good dark matter candidat…
New opportunities for axion dark matter searches in nonstandard cosmological models
Paola Arias, Nicolás Bernal, Dimitrios Karamitros +3
We study axion dark matter production from a misalignment mechanism in scenarios featuring a general nonstandard cosmology. Before the onset of Big Bang nucleosynthesis, the energy…
Frozen-in fermionic singlet dark matter in non-standard cosmology with a decaying fluid
Paola Arias, Dimitrios Karamitros, Leszek Roszkowski
We perform a detailed study of dark matter production via freeze-in under the assumption that some fluid dominates the early Universe before depositing its energy to the plasma cau…
