“…That is, if dark matter was non-thermally produced resulting in a larger self annihilation cross-section, then cross sections for dark matter particles deduced from LHC -when used to calculate the thermal relic density -would result in an unacceptably low cosmological abundance and would be in surprising disagreement with e.g. the WMAP data [40]. Of course, the explanation could also lie elsewhere, e.g.…”

“…as a consequence of more than one dark matter particle. Thus, we are lead to the possibility of a 'dark matter inverse problem' [40] -stressing the importance of combining collider, astrophysical (direct/indirect detection), and cosmological probes in order to obtain a complete understanding of both the microscopic and cosmological nature of dark matter.…”

The origin of dark matter as a thermal relic offers a compelling way in which the early universe was initially populated by dark matter. Alternative explanations typically appear exotic compared to the simplicity of thermal production. However, recent observations and progress from theory suggest that it may be necessary to be more critical. This is important because ongoing searches probing the microscopic properties of dark matter typically rely on the assumption of dark matter as a single, unique, thermal relic. On general grounds I will argue that non-thermal production of dark matter seems to be a robust prediction of physics beyond the standard model. However, if such models are to lead to realistic phenomenology, they must sit in a restrictive theoretical framework. As we will show, as a consequence of such restrictions, viable models will result in concrete and testable predictions. Although many challenges remain, the non-thermal component of such models may offer a new way to test string theories that are formulated to provide realistic particle physics near the electroweak scale.

“…By definition, the WIMP has negligible interactions with matter, it may be detected only indirectly if and only if the background collision products are detected and subtracted (Kane & Watson, 2008). These experiments could show that WIMPs can be created, but it would still require a direct detection experiment to show that they exist in sufficient numbers in the galaxy to account for the dark matter needed by the Big Bang theory.…”

An Alternative Cosmology to the Big Bang–Dispersive Extinction Theory of Red Shift

A brief review is given to the fundamental difficulties facing the Big Bang Theory, with the emphases on the geocentric nature, the extreme violation of the conservation laws of mass and energy, the violation of Maxwell's velocity distribution, the horizon problem, the extreme instability and the dark matter problem. The historical alternatives and their problems are reviewed. The DET is then presented as a new alternative interpretation of the cosmic redshift, and therefore, as a new alternative to the Big Bang cosmology. The existing experimental evidences to vindicate or falsity DET versus Big Bang theory are discussed. Experiments for detailed tests of the DET-the redshift is proportional to the square of the linewidth and inversely proportional to the cube of the wavelength-are also proposed.

In this paper, we generalize the simplified Dark Matter models with graviton mediator to the curved space-time, in particular to the de Sitter space. We obtain the generating functional of the Green's functions in the Euclidean de Sitter space for the covariant free gravitons. We determine the generating functional of the interacting theory between Dark Matter particles and the covariant gravitons. Also, we calculate explicitly the 2point and 3-point interacting Green's functions for the symmetric traceless divergence-less covariant graviton. The results derived here are general in the sense that they do not depend on a particular model for the Dark Matter component and they show that the quantum effects of the interaction between the Dark Matter and the gravitons in the de Sitter space are computable by the methods of the standard Quantum Field Theory techniques.
