Nonthermal “WIMP miracle”

A Non-Thermal WIMP Miracle

South Korea: Economic Miracle by Policy Miracle?

Historical, cultural and institutional factors certainly did have a positive impact on the economic growth in South Korea and the other East Asian newly industrialising economies. However, these factors would not have been of any importance without governmental influence. Particularly in South Korea, a strong state with highly respected and qualified bureaucrats could play a central role in sti...

Optimizing WIMP directional detectors

We study the dependence of the exposure required to directly detect a WIMP directional recoil signal on the capabilities of a directional detector. Specifically we consider variations in the nuclear recoil energy threshold, the background rate, whether the detector measures the recoil momentum vector in 2 or 3 dimensions and whether or not the sense of the momentum vector can be determined. We ...

Secluded WIMP Dark Matter

We consider a generic mechanism via which thermal relic WIMP dark matter may be decoupled from the Standard Model, namely through a combination of WIMP annihilation to metastable mediators with subsequent delayed decay to Standard Model states. We illustrate this with explicit examples of WIMPs connected to the Standard Model by metastable bosons or fermions. In all models, provided the WIMP ma...

WIMP direct detection overview ∗

This review on weakly interacting massive particle (WIMP) dark matter direct detection focuses on experimental approaches and the corresponding physics basics. The presentation is intended to provide a quick and concise introduction for non-specialists to this fast evolving topic of astroparticle physics.
