2701por Ciafaloni, Paolo, Cirelli, Marco, Comelli, Denis, De Simone, Andrea, Riotto, Antonio, Urbano, Alfredo“…The cross section for a Majorana Dark Matter particle annihilating into light fermions is helicity suppressed. …”

2702“…We discuss the positive indications of a possible dark matter signal in direct detection experiments in terms of a mechanism of interaction between the dark matter particle and the nuclei occurring via the exchange of a light mediator, resulting in a long-range interaction. …”

2703por Genest, M-H“…Supersymmetry is an appealing theory beyond the Standard Model which provides a natural Dark Matter candidate. First ATLAS searches for signals of supersymmetry in proton-proton collisions at the LHC are reported here for the 0- and 1-lepton channels; the full data sample recorded in the 2010 LHC run, corresponding to an integrated luminosity of 35 pb^{-1} , has been analysed.…”

2705“…We relate the mechanism of matter creation in the universe after inflation to a simple and universal mathematical property of extended N > 1 supergravities and related compactifications of superstring theory. …”

2706por Frandsen, Mads T., Kahlhoefer, Felix, McCabe, Christopher, Sarkar, Subir, Schmidt-Hoberg, Kai“…We study the impact of the assumed velocity distribution of galactic dark matter particles on the interpretation of results from nuclear recoil detectors. …”

2707“…This symmetry ensures stability of the vector fields making them viable dark matter candidates, while evading the usual electroweak constraints. …”

2708“…We study the implications of these LHC Higgs searches for Higgs portal models of dark matter in a rather model independent way. Their impact on the cosmological relic density and on the direct detection rates are studied in the context of generic scalar, vector and fermionic thermal dark matter particles. …”

2713por Cirelli, Marco“…I review in a schematic way the current status of indirect searches for Dark Matter: I list the main relevant experimental results of the recent years and I discuss the excitements and disappointments that their phenomenological interpretations in terms of almost-standard annihilating Dark Matter have brought along. …”

2716“…In the context of Higgs-portal models of dark matter, we then discuss how the LHC limits on the invisible Higgs branching fraction impose strong constraints on the dark matter scattering cross section on nucleons probed in direct detection experiments.…”

2718por d'Enterria, David“…Data measured at center-of-mass energies sqrt(s_NN) = 2.76 TeV in lead-lead (Pb-Pb) collisions are compared to proton-proton (p-p) measurements in order to extract information on the properties of hot and dense strongly-interacting matter.…”
