5203“…Held in October 2008, it gathered in Brussels most of the leading figures working on the quantum theory of condensed matter, addressing some of the most profound open problems in the field. …”

5204“…In this article, we review the prospects for the Fermi satellite (formerly known as GLAST) to detect gamma rays from dark matter annihilations in the Central Region of the Milky Way, in particular on the light of the recent astrophysical observations and discoveries of Imaging Atmospheric Cherenkov Telescopes. …”

5206“…We propose a scenario where Dark Matter (DM) annihilates into an intermediate state which travels a distance $\lambda = v/\Gamma$ on the order of galactic scales and then decays to Standard Model (SM) particles. …”

5207por Cyburt, Richard H., Ellis, John, Fields, Brian D., Luo, Feng, Olive, Keith A., Spanos, Vassilis C.“…The decays of massive gravitinos into neutralino dark matter particles and Standard Model secondaries during or after Big-Bang nucleosynthesis (BBN) may alter the primordial light-element abundances. …”

5210por Rasanen, Syksy“…We derive the relationship of the redshift and the angular diameter distance to the average expansion rate for universes which are statistically homogeneous and isotropic and where the distribution evolves slowly, but which have otherwise arbitrary geometry and matter content. The relevant average expansion rate is selected by the observable redshift and the assumed symmetry properties of the spacetime. …”

5212“…In the Majorana neutrino case, only gravitino is a natural dark matter candidate. On the other hand, in the Dirac neutrino case, the right-handed sneutrino can be also a dark matter candidate as it gets mass only from SUSY breaking. …”

5218“…Cosmological analysis based on currently available observations are unable to rule out a sizeable coupling among the dark energy and dark matter fluids. We explore a variety of coupled dark matter-dark energy models, which satisfy cosmic microwave background constraints, in light of low redshift and near universe observations. …”

5219por Esteves, J.N., Joaquim, F.R., Joshipura, A.S., Romao, J.C., Tortola, M.A., Valle, J.W.F.“…We show that, if the Majoron becomes massive, such seesaw scenario provides a viable candidate for decaying dark matter, consistent with cosmic microwave background lifetime constraints that follow from current WMAP observations. …”
