چکیده
We study the possibility of mixed dark matter obtained through the phase space distribution of a single particle. An example is offered in the context of SUSY models with a Peccei-Quinn symmetry. Axinos in the 100 keV range can naturally have both thermal and non-thermal components. The latter one arises from the lightest neutralino decays and derelativizes at z ∼ 10 4 .

The impact of a kination-dominated phase generated by a quintessential exponential model on the thermal abundance of gravitinos and axinos is investigated. We find that their abundances become proportional to the transition temperature from the kination to the radiation era; since this temperature is significantly lower than the initial (“reheating”) temperature, the abundances decrease with re...

It is nowadays clear that General Relativity cannot be the definitive theory of Gravitation. The attempts to recover it, with respect to the latest observative data, lead in fact to very strange physical entities as the Dark Energy & Dark Matter. On the other hand, the attempts to produce generalized theories give rise to mathematical difficulties that need workarounds which, in turn, generate ...

We re-examine collisional annihilation of superheavy dark matter particles in dark matter density spikes in the galactic halo as a possible source of ultrahigh energy cosmic rays. We estimate the possible flux in a way that does not depend on detailed assumptions about the density profiles of dark matter clumps. The result confirms that collisional annihilation is compatible with annihilation c...

One of the possible explanations for the dark matter needed in the standard cosmological model is so-called warm dark matter, in the form of right-handed (“sterile”) neutrinos with a mass in the keV range. I describe how various properties of QCD at temperatures of a few hundred MeV play an important role in the theoretical computations that are needed for consolidating or falsifying this scena...
