WIMP dark matter in bulk viscous non-standard cosmologies
Esteban González, Carlos Maldonado, N. Stefanía Mite +1
In this paper, we explored an extension of the classical non-standard cosmological scenario in which the new field, , which interacts with the radiation component in the early u…
Dark Matter in a bi-metric universe
Carlos Maldonado, Fernando Mendez
We study the possibility to describe dark matter in a model of the universe with two scale factors and a non-standard Poisson bracket structure characterized by the deformation par…
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…
Bi-metric Universe with Matter
Carlos Maldonado, Fernando Mendez
We analyze the early stage of evolution of a universe with two scale factors proposed in [1] when matter is present. The scale factors describe two causally disconnected patches of…
Ultraviolet Freeze-in and Non-Standard Cosmologies
Nicolás Bernal, Fatemeh Elahi, Carlos Maldonado +1
A notable feature of UV freeze-in is that the relic density is strongly dependent on the highest temperatures of the thermal bath, and a common assumption is that the relevant 'hig…
Reconstructing Non-standard Cosmologies with Dark Matter
Paola Arias, Nicolás Bernal, Alan Herrera +1
Once dark matter has been discovered and its particle physics properties have been determined, a crucial question rises concerning how it was produced in the early Universe. If its…
Establishing the Dark Matter Relic Density in an Era of Particle Decays
Carlos Maldonado, James Unwin
If the early universe is dominated by an energy density which evolves other than radiation-like the normal Hubble-temperature relation is broken and dark matter reli…
Testing a new WISP Model with Laboratory Experiments
P. D. Alvarez, Paola Arias, Carlos Maldonado
We explore the phenomenological consequences of a model with axion-like particles and hidden photons mixing with photons. In this model, the hidden photon is directly coupled to th…
A two particle hidden sector and the oscillations with photons
Pedro Diego Alvarez, Paola Arias, Carlos Maldonado
We present a detailed study of the oscillations and optical properties for vacuum, in a model for the dark sector that contains axion-like particles and hidden photons. In this mod…
