Search for Neutrino Mass and Dark Matter in Underground Experiments
In this lecture we shall discuss two central problems of particle physics and cosmology. The neutrino mass is one of the key quantities in grand unified theories, and at the same time candidate for hot dark matter in the Universe. Supersymmetry is regarded as the most natural extension of present particle physics theories. The lighest SUSY particle, usually assumed to be the neutralino, is the ...
متن کاملDark Matter Experiments at Boulby Mine
The Boulby Dark Matter Collaboration (BDMC) is running several experiments for particle (WIMP) dark matter search in the Underground Boulby Laboratory. These include a liquid xenon detector (ZEPLIN I) and a low pressure gas TPC with directional sensitivity (DRIFT I). Next stage double-phase xenon detectors ZEPLIN II and ZEPLIN III, and a new TPC DRIFT II will be installed at Boulby in a few mon...
متن کاملDirac Neutrino Dark Matter
We investigate the possibility that dark matter is made of heavy Dirac neutrinos with mass m ∈ [O(1) GeV– a few TeV] and with suppressed but non-zero coupling to the Standard Model Z as well as a coupling to an additional Z ′ gauge boson. The first part of this paper provides a model-independent analysis for the relic density and direct detection in terms of four main parameters: the mass, the ...
متن کاملNeutrino Dark Matter
There is a puzzling contradiction: direct observations favor a low-mass density universe, but the only model which fits universe structure over more than three orders of magnitude in distance scale has a mix of hot (neutrino) and cold dark matter constituting a critical density universe. If all present indications for neutrino mass are valid, that hot dark matter is shared by two neutrino speci...
متن کاملNeutrino Probes of the Nature of Light Dark Matter
Dark matter particles gravitationally trapped inside the Sun may annihilate into Standard Model particles, producing a flux of neutrinos. The prospects of detecting these neutrinos in future multi-kt neutrino detectors designed for other physics searches are explored here. We study the capabilities of a 34/100 kt liquid argon detector and a 100 kt magnetized iron calorimeter detector. These det...
