TL;DR: The present experimental status of dark matter theory and experiment is overview, which includes current bounds and recent claims and hints of a possible signal in a wide range of experiments: direct detection in underground laboratories, gamma-ray, cosmic ray, x-rays, neutrino telescopes, and the LHC.

TL;DR: In this paper, it was shown that axinos produced in the early universe in the decay of the lightest neutralinos are a compelling candidate for cold dark matter, and axinos may well provide the main component of the missing mass in the Universe because their relic density is naturally of the order of the critical density.

TL;DR: In this paper, the authors classify thermally and non-thermally produced dark matter (DM) models into two broad categories: one involving bosonic coherent motion (BCM) and the other involving WIMPs.

TL;DR: In this paper, the axino mass in the range of tens of MeV to several GeV (depending on the scenario) is identified as corresponding to cold axino relics if the reheating temperature TR is less than about 5 × 104 GeV.

TL;DR: In this paper, a comprehensive exploration of the Constrained MSSM parameter space employing a Markov Chain Monte Carlo technique and a Bayesian analysis is performed, which includes uncertainties arising from theoretical approximations as well as from residual experimental errors of relevant Standard Model parameters.
