A PRELIMINARY ANALYSIS OF THE ENERGY TRANSFER BETWEEN THE DARK SECTORS OF THE UNIVERSE
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
We study the mutual interaction between the dark sectors (dark matter and dark energy) of the Universe by resorting to the extended thermodynamics of irreversible processes and constrain the former with supernova type Ia ...
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 ...
Dark energy parametrizations and their effect on dark halos
(Iop Publishing Ltd, 2006-07-01)
There are a plethora of dark energy parametrizations that can fit current supernovae Ia data. However, these data are only sensitive to redshifts up to order one. In fact, many of these parametrizations break down at higher ...

The imprint of the interaction between dark sectors in galaxy clusters
(IOP PUBLISHING LTD, 2010)
Based on perturbation theory, we study the dynamics of how dark matter and dark energy in the collapsing system approach dynamical equilibrium when they are in interaction. We find that the interaction between dark sectors ...

THE HIGGS PORTAL and AN UNIFIED MODEL FOR DARK ENERGY and DARK MATTER
(World Scientific Publ Co Pte Ltd, 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 ...
