Title: Long-lived light mediator to dark matter and primordial small scale spectrum

Abstract

We calculate the early universe evolution of perturbations in the dark matter energy density in the context of simple dark sector models containing a GeV scale light mediator. We consider the case that the mediator is long-lived, with lifetime up to a second, and before decaying it temporarily dominates the energy density of the universe. We show that for primordial perturbations that enter the horizon around this period, the interplay between linear growth during matter domination and collisional damping can generically lead to a sharp peak in the spectrum of dark matter density perturbation. Finally, as a result, the population of the smallest DM halos gets enhanced. Possible implications of this scenario are discussed.

Signatures of non-gaussianity in the isocurvature modes of primordial black hole dark matter

Journal Article Young, Sam ; Byrnes, Christian T., E-mail: S.M.Young@sussex.ac.uk, E-mail: C.Byrnes@sussex.ac.uk - Journal of Cosmology and Astroparticle Physics

Primordial black holes (PBHs) are black holes which may have formed very early on during the radiation dominated era in the early universe. We present here a method by which the large scale perturbations in the density of primordial black holes may be used to place tight constraints on non-gaussianity if PBHs account for dark matter (DM) . The presence of local-type non-gaussianity is known to have a significant effect on the abundance of primordial black holes, and modal coupling from the observed CMB scale modes can significantly alter the number density of PBHs that form within different regions ofmore »« less

Primordial black hole evaporation and dark matter production. II. Interplay with the freeze-in or freeze-out mechanism

Journal Article Cheek, Andrew ; Heurtier, Lucien ; Perez-Gonzalez, Yuber F. ; ... - Physical Review D

We study how the evaporation of primordial black holes (PBHs) can affect the production of dark matter (DM) particles through thermal processes. We consider fermionic DM interacting with Standard Model particles via a spin-1 mediator in the context of a freeze-out or freeze-in mechanism. We show that when PBHs evaporate after dominating the Universe’s energy density, PBHs act as a source of DM and continuously inject entropy into the visible sector that can affect the thermal production in three qualitatively different ways. We compute the annihilation cross sections which account for the interactions between and within the PBH produced andmore »« less

EVOLUTION OF PRIMORDIAL STARS POWERED BY DARK MATTER ANNIHILATION UP TO THE MAIN-SEQUENCE STAGE

Journal Article Hirano, Shingo ; Umeda, Hideyuki ; Yoshida, Naoki - Astrophysical Journal

Primordial stars formed in the early universe are thought to be hosted by compact dark matter (DM) halos. If DM consists of weakly interacting massive particles (WIMPs), such stars may be powered by DM annihilation during the early phases of their evolution. We study the pre-main-sequence evolution of the primordial star using a detailed stellar evolution code under the assumption that the annihilation of adiabatically contracted WIMP DM within the star provides sufficient energy to sustain the stellar equilibrium. We follow the evolution of accreting stars using several gas mass accretion rates derived from cosmological simulations. We show that themore »« less
