GENIUS - A new underground observatory for non-accelerator particle physics

  title={GENIUS - A new underground observatory for non-accelerator particle physics},
  author={H. V. Klapdor-kleingrothaus},
The GENIUS (Germanium in Liquid Nitrogen Underground Setup) project has been proposed in 1997 [2] as first third generation double beta decay project, with a sensitivity aiming down to a level of an effective neutrino mass of 〈mν〉 < 0.01 eV or less. Such sensitivity is important to fix the structure of the neutrino mass matrix with high accuracy, which cannot be done by neutrino oscillation experiments alone. GENIUS will allow broad access also to many other topics of physics beyond the… Expand

Towards a Background-Free ββ-Decay Experiment Using the EDELWEISS Cryogenic Ge Detectors
The present generation of double-beta experiments is limited by two main backgrounds: surface alpha interactions and Compton interactions from high-energy gamma-ray lines. Using the detectorExpand
Dark matter, light top squarks, and electroweak baryogenesis
We examine the neutralino relic density in the presence of a light top squark, such as the one required for the realization of the electroweak baryogenesis mechanism, within the minimalExpand
Supersymmetric Origin of Matter
The minimal supersymmetric extension of the standard model (MSSM) can provide the correct neutralino relic abundance and baryon number asymmetry of the universe. Both may be efficiently generated inExpand
Dark matter searches : Technology and backgrounds
The current status of direct dark matter searches is reviewed, with special emphasis on the effect of various backgrounds to the sensitivity attainable by this technology. The current leader inExpand
Model of neutrino effective masses
It is shown that an effective (nonrenormalizable) coupling of lepton multiplets to scalar triplets in the 331 model with sterile/exotic neutrinos, can be a good way for generating neutrino masses ofExpand
Direct detection of dark matter in supersymmetric models
We evaluate neutralino–nucleon scattering rates in several well-motivated supersymmetric models, and compare against constraints on the neutralino relic density, BF(b→sγ) as well as the muonExpand
Spin in the dark matter problem
Weakly interacting massive particles (WIMPs) are among the main candidates for the relic dark matter (DM). The idea of direct DM detection relies on elastic spin-dependent (SD) and spin-independentExpand
