Superheavy dark matter in R2-cosmology

چکیده

The conventional Friedmann cosmology is known to be in tension with the existence of stable particles having interaction strength typical for supersymmetry and heavier than several TeV. A possible way save life such may a modification standard cosmological expansion law that density these heavy relics would significantly reduced. We study particle creation Starobinsky inflationary model different decay channels scalaron. It shown process thermalization superheavy coupling GUT SUSY could created equal observed dark matter.

Superheavy dark matter

We show that, contrary to the standard lore, dark matter may be superheavy (many orders of magnitude larger than the weak scale). We show that massive particles may be produced naturally during the transition from the inflationary phase to either a matter-dominated or radiation-dominated phase as a result of the expansion of the background spacetime acting on vacuum quantum fluctuations of the ...

Superheavy Dark Matter A

In the standard dark matter scenarios, WIMPs are usually considered to have once been in local thermodynamic equilibrium (LTE), and their present abundance is determined by their self-annihilation cross section. In that case, unitarity and the lower bound on the age of the universe constrains the mass of the relic to be less than 500 TeV. 1 On the other hand, if the DM particles never attained ...

Dark 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...

Hot 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...

Superheavy Dark Matter with Discrete Gauge Symmetries

We show that there are discrete gauge symmetries protect naturally heavy X particles from decaying into the ordinary light particles in the supersymmetric standard model. This makes the proposal very attractive that the superheavy X particles constitute a part of the dark matter in the present universe. It is more interesting that there are a class of discrete gauge symmetries which naturally a...
