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…
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…
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.
Scalar fields and cosmological attractor solutions
F. Rosati
Results of a general study on the dynamics of cosmological scalar fields with arbitrary potentials are presented. Exact and approximate attractor solutions are found, with applicat…
Can the Inflaton and the Quintessence scalar be the same field?
Francesca Rosati
The most recent cosmological data point in the direction of a cosmological constant dominated universe. A suitable candidate for providing the required acceleration is a rolling sc…
Supersymmetric Quintessence
Francesca Rosati
Recent data point in the direction of a cosmological constant dominated universe. We investigate the role of supersymmetric QCD with N_f < N_c as a possible candidate for dynamical…
