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…
Higgs production and decay in the little Higgs model
C. Dib, R. Rosenfeld, A. Zerwekh
We analyse the consequences of the little Higgs model for double Higgs boson production at the LHC and for the partial decay width of the Higgs into two photons. In particular, we…
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…
Anomalous Higgs Couplings in Triple Gauge Boson Production at the NLC
F. de Campos, S. M. Lietti, S. F. Novaes +1
We present the sensitivity limits on the coefficients of a dimension-6 effective operators that parametrizes the possible effects of new physics beyond the Standard Model. Our resu…
