Cosmology and Astrophysics of Minimal Dark Matter
We consider DM that only couples to SM gauge bosons and fills one gauge multiplet, e.g. a fermion 5-plet (which is automatically stable), or a wino-like 3-plet. We revisit the computation of the cosmological relic abundance including non-perturbative corrections. The predicted mass of e.g. the 5-plet increases from 4.4TeV to 10TeV, and indirect detection rates are enhanced by 2 orders of magnit...
متن کاملTheory of Dark Energy and Dark Matter
In (T. Ma and S. Wang. Gravitational field equations and theory of dark matter and dark energy, Discrete and Continuous Dynamical Systems, Ser. A, 34(2): 335–366, 2014; arXiv:1206.5078v2), a new set of gravitational field equations are derived based only on 1) the Einstein principle of general relativity, and 2) the principle of interaction dynamics, due to the the presence of dark energy and d...
متن کاملDark Matter: the Connection with Gamma-Ray Astrophysics Discovering Dark Matter particles with astrophysical observations
We review the status of indirect Dark Matter searches, focusing in particular on the connection with gamma-ray Astrophysics, and on the prospects for detection with the upcoming space telescope GLAST and Air Cherenkov Telescopes such as CANGAROO, HESS, MAGIC and VERITAS. After a brief introduction where we review the fundamental motivations for indirect searches, we tackle the question of wheth...
متن کاملDark Matter Theory
I evaluate the dark matter budget and describe baryonic dark matter candidates and their detectability. Dark matter issues in galaxy formation theory are discussed, and I review the prospects for detecting nonbaryonic dark matter. Indirect detection via halo annihilations of the favored dark matter candidate, the SUSY LSP, provides a potential signal. The relic density of dark matter particles ...
متن کاملDark Matter Theory
The dark matter problems remains as one of the outstanding enigmas of particle physics and cosmology. Chances for solving the problem of the identity of dark matter depends on its nature, but for the set with supporting evidence from early universe theory, WIMPs (weakly interacting massive particles) there is great hope that the presently fast experimental progress may produce conclusive answer...
