2083“…The Minimal Supersymmetric Standard Model has a candidate dark matter particle in its spectrum and may be able to generate the baryon asymmetry of the Universe (BAU) at the electroweak phase transition. …”

2088“…The book deals with the liquid and gaseous phases of nuclear matter, as well as with the experimental routes to achieve transformation between them.Theoretical models are introduced from the ground up and with increasing complexity to describe nuclear matter from a statistical and thermodynamical point of view. …”

2094“…We show that massive sterile neutrinos mixed with the ordinary ones may be produced in the early universe in the right amount to be natural warm dark matter particles. Their mass should be in the range 1-40 keV and the corresponding mixing angles sin$^2 2 \theta=10^{-8}$ to $10^{-11}$ for mixing with $\num$ or $\nut$, and mixing with $\nu_e$ is marginally allowed with mass about 30 keV and sin$^2\theta \approx 10^{-11}$.…”

2095por Olive, Keith A“…Accelerator constraints on the parameter space of the minimal supersymmetric extension of the standard model are analyzed and contrasted with the parameter space yielding dark matter which is allowed by the cosmological constraints on the relic density. …”

2097por Giudice, Gian F., Kolb, Edward W., Riotto, Antonio, Semikoz, Dmitry V., Tkachev, Igor I.“…Standard Model neutrinos are not usually considered plausible dark matter candidates because the usual treatment of their decoupling in the early universe implies that their mass must be sufficiently small to make them ``hot'' dark matter. …”

2098por Roszkowski, Leszek“…At higher T_R and lower mass, axinos could constitute warm dark matter. In the scenario with axinos as stable relics the gravitino problem finds a natural solution. …”
