A closer look at dark matter production in exponential growth scenarios

Journal of High Energy Physics
We investigate a recently proposed non-thermal mechanism for dark matter production, in which a small initial dark matter (χ) number density undergoes exponential growth through scatterings with bath particles (ϕ) in the early universe (χϕ → χχ).

The Diurnal Variation of the Wimp Detection Event Rates in Directional Experiments

, 2009
The recent WMAP data have confirmed that exotic dark matter together with the vacuum energy (cosmological constant) dominate in the flat Universe. Modern particle theories naturally provide viable cold dark matter candidates with masses in the GeV-TeV ...

Lepton collider as a window to reheating via freezing in dark matter detection. Part II

Journal of High Energy Physics
Dark matter (DM) genesis via Ultraviolet (UV) freeze-in embeds the seed of reheating temperature and dynamics in its relic density. Thus, discovery of such a DM candidate can possibly open the window for post-inflationary dynamics.

Issues in the Investigations of the Dark Matter Phenomenon in Galaxies: Parcere Personis, Dicere de Vitiis

Universe
It is always more evident that the kinematics of galaxies provide us with unique information on the Nature of the dark particles and on the properties of the galaxy Dark Matter (DM) halos.

Integral and Light Dark Matter

, 2004
The nature of Dark Matter remains one of the outstanding questions of modern astrophysics. The success of the Cold Dark Matter cosmological model argues strongly in favor of a major component of the dark matter being in the form of elementary particles ...

Conversions in two-component dark sectors: a phase space level analysis

Journal of High Energy Physics
Conversions between the states in the dark sector affect not only their number densities but also their momentum distributions. In this work we study a phenomenologically motivated two-component dark matter scenario, based on the Coy Dark Matter model ...

Prospects of detecting cosmic ray up-scattered dark matter with DUNE

Journal of High Energy Physics
Detection of sub-GeV dark matter (DM) particles in direct detection experiments is inherently difficult, as their low kinetic energies in the galactic halo are insufficient to produce observable recoils of the heavy nuclei in the detectors.
