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 کاملDark Matter in Cosmology
The last two decades in cosmological research have been an exciting time, and produced an exciting product: we now have in hand a “standard model” of cosmology. While several aspects of this model remain mysterious, its predictions are in remarkable accord with a vast range of observational data. A key aspect of this model, and one of the aforementioned mysteries, is the dark matter: a cold, co...

متن کاملHot Dark Matter in Cosmology
1 Historical Summary Cosmological dark matter in the form of neutrinos with masses of up to a few electron volts is known as hot dark matter. In 1979-83, this appeared to be perhaps the most plausible dark matter candidate. Such HDM models of cosmological structure formation led to a top-down formation scenario, in which superclusters of galaxies are the first objects to form, with galaxies and...
متن کاملThe dark side of cosmology: dark matter and dark energy.
A simple model with only six parameters (the age of the universe, the density of atoms, the density of matter, the amplitude of the initial fluctuations, the scale dependence of this amplitude, and the epoch of first star formation) fits all of our cosmological data . Although simple, this standard model is strange. The model implies that most of the matter in our Galaxy is in the form of "dark...
