Journal ArticleDOI
Freeze-in production of FIMP dark matter
Lawrence J. Hall,Lawrence J. Hall,Lawrence J. Hall,Karsten Jedamzik,John March-Russell,Stephen M. West,Stephen M. West +6 more
TL;DR: In this paper, the authors propose an alternate, calculable mechanism of dark matter genesis, "thermal freeze-in", involving a Feebly Interacting Massive Particle (FIMP) interacting so feebly with the thermal bath that it never attains thermal equilibrium.
Journal ArticleDOI
Kerr Black Holes as Particle Accelerators to Arbitrarily High Energy
TL;DR: It is shown that intermediate mass black holes conjectured to be the early precursors of supermassive black holes and surrounded by relic cold dark matter density spikes can act as particle accelerators with collisions, in principle, at arbitrarily high center-of-mass energies in the case of Kerr black holes.

TL;DR: In this paper, a set of simplified models for dark matter and its interactions with the Standard Model particles are presented, and the guiding principles underpinning these simplified models are spelled out, and some suggestions for implementation are presented.

Journal ArticleDOI
WIMPonium and Boost Factors for Indirect Dark Matter Detection
TL;DR: In this article, it was shown that WIMP dark matter can annihilate via long-lived "WIMPonium" bound states in reasonable particle physics models of dark matter (DM).
