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,…
N=1 Supergravity Chaotic Inflation in the Braneworld Scenario
M. C. Bento, O. Bertolami
We study a N=1 Supergravity chaotic inflationary model, in the context of the braneworld scenario. It is shown that successful inflation and reheating consistent with phenomenologi…
A Two-Field Quintessence Model
M. C. Bento, O. Bertolami, N. C. Santos
We study the dynamics of a quintessence model based on two interacting scalar fields. The model can account for the (recent) accelerated expansion of the Universe suggested by astr…
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…
