Reconstruction of interacting dark energy models from parameterizations
Rogerio Rosenfeld
Models with interacting dark energy can alleviate the cosmic coincidence problem by allowing dark matter and dark energy to evolve in a similar fashion. At a fundamental level, the…
Variable-Mass Dark Matter and the Age of the Universe
Urbano França, Rogerio Rosenfeld
Models with variable-mass particles, called VAMPs, have been proposed as a solution to the cosmic coincidence problem that plagues dark energy models. In this contribution we make…
Cosmological Bounds on an Invisibly Decaying Higgs Boson
O. Bertolami, M. C. Bento, R. Rosenfeld
We derive bounds on the Higgs boson coupling to a stable light scalar which is regarded as a collisional dark matter candidate. We study the behaviour of this scalar,…
Self-Interacting Scalar Dark Matter and Higgs Decay
M. C. Bento, O. Bertolami, R. Rosenfeld +1
Self-interacting dark matter has been suggested in order to overcome the difficulties of the Cold Dark Matter model on galactic scales. We argue that a scalar gauge singlet coupled…
