Scale-invariant scalar field dark matter through the Higgs portal
Catarina Cosme
We introduce an oscillating scalar field coupled to the Higgs that can account for all dark matter in the Universe. Due to an underlying scale invariance of this model, the dark sc…

Can dark matter drive electroweak symmetry breaking?
Catarina Cosme, João G. Rosa, Orfeu Bertolami
We consider the possibility of an oscillating scalar field accounting for dark matter and dynamically controlling the spontaneous breaking of the electroweak symmetry through a Hig…

Scalar field dark matter and the Higgs field
Orfeu Bertolami, Catarina Cosme, João G. Rosa
We discuss the possibility that dark matter corresponds to an oscillating scalar field coupled to the Higgs boson. We argue that the initial field amplitude should generically be o…
