Possible influence of Dark Energy on the Dark Matter Relic Abundance
Antonio Masiero, Francesca Rosati
Although a direct interaction between WIMP CDM candidates and scalar Quintessence fields (sources of Dark Energy) poses severe phenomenological threats, yet it is possible that the…
Cosmological evolution of Alpha driven by a general coupling with Quintessence
Valerio Marra, Francesca Rosati
A general model for the cosmological evolution of the fine structure constant αdriven by a typical Quintessence scenario is presented. We consider a coupling between the Quintessen…
Dark Energy and the Dark Matter relic abundance
Francesca Rosati
Two mechanisms by which the Quintessence scalar could enhance the relic abundance of dark matter particles are discussed. This effect can have an impact on supersymmetric candidate…
Enhancement of Dark Matter Abundance in Scalar-Tensor Dark Energy
R. Catena, N. Fornengo, A. Masiero +2
In Scalar-Tensor theories of gravity, the expansion rate of the universe in the past may differ considerably from the standard one. After imposing the constraints coming from nucle…
Dark Matter Relic Abundance and Scalar-Tensor Dark Energy
R. Catena, N. Fornengo, A. Masiero +2
Scalar-tensor theories of gravity provide a consistent framework to accommodate an ultra-light quintessence scalar field. While the equivalence principle is respected by constructi…
Quintessence and the dark matter abundance
Francesca Rosati
Results of a recent study on how the Quintessence scalar could affect the relic abundance of dark matter particles are presented.
