The higgs portal and an unified model for dark energy and dark matter
(2008-12-10)
We examine a scenario where the Higgs boson is coupled to an additional Standard Model singlet scalar field from a hidden sector. We show that, in the case where this field is very light and has already relaxed to its ...
Dark matter to dark energy transition in k-essence cosmologies
(World Scientific, 2005-12)
We implement the transition from dark matter to dark energy in k-essence cosmologies for a very large set of kinetic functions F, in a way alternative to recent proposals which use generalized Chaplygin gas and transient ...
Z(2) SIMP dark matter
(Iop Publishing Ltd, 2016-01-01)
Dark matter with strong self-interactions provides a compelling solution to several small-scale structure puzzles. Under the assumption that the coupling between dark matter and the Standard Model particles is suppressed, ...
Dark energy parametrizations and their effect on dark halos

Consequences of dark matter-dark energy interaction on cosmological parameters derived from type Ia supernova data
(American Physical Soc, 2014)
DBI models for the unification of dark matter and dark energy
(Springer/Plenum Publishers, 2010-05)
We propose a model based on a DBI action for the unification of dark matter and dark energy. This is supported by the results of the study of its background behavior at early and late times, and reinforced by the analysis ...

Interacting dark matter and cosmic acceleration
(EDP SciencesSocietà Italiana di FisicaSpringer Berlin Heidelberg, 2020)
We study the effect of an explicit interaction between two scalar fields components describing dark matter in the context of a recent proposal framework for interaction. We find that, even assuming a very small coupling, ...
Consequences of dark matter-dark energy interaction on cosmological parameters derived from type Ia supernova data
(American Physical Soc, 2007-04-01)
Models where the dark matter component of the Universe interacts with the dark energy field have been proposed as a solution to the cosmic coincidence problem, since in the attractor regime both dark energy and dark matter ...
