Titre |
Exploring exponential growth scenarios for dark matter production |
|
Résumé |
In this talk, I shall focus on a particular non-thermal production mechanism where
dark matter is produced through
scatterings with the bath particles. The scatterings are such that they lead to
the exponential growth in the early
universe which stops with the reaction rate becoming Boltzmann suppressed. The
results are computed in this scenario
under the assumption that dark matter traces the equilibrium distribution of
either the standard model or some hidden
sector bath. Since dark matter is produced non-thermally the above assumption may
not hold. We determine the distribution
function of dark matter by solving the Boltzmann-equation and find that the
obtained distribution exhibits different
behavior from the equilibrium pattern. In particular, it is sensitive to the
mechanism populating the initial density of
dark matter. |
