GENIUS: Issues
Scientific Issues of the Genius Project
The GENIUS experiment addresses two major questions of particle and astroparticle science:

Dark Matter Search and Double Beta Decay

The experiment will allow to probe neutrino masses down to 10-(2-3) eV. GENIUS will test the structure of the neutrino mass matrix, and therefore implicitly neutrino oscillation parameters comparable or superior in sensitivity to the best proposed dedicated terrestrial neutrino oscillation experiments. If the 10-3 eV level is reached, GENIUS will even allow to test the large angle MSW solution of the solar neutrino problem. Even in its first stage GENIUS will confirm or rule out degenerate or inverted neutrino mass scenarios, which have been widely discussed in the literature as a possible solution to current hints on finite neutrino masses and also test the ve -> vµ hypothesis of the atmospheric neutrino problem.

GENIUS would contribute to the search for R-parity violating SUSY and right-handed W-bosons on a scale similar or superior to LHC. In addition, GENIUS would largely improve the current neutrinoless double beta decay searches for R-parity conserving SUSY and leptoquarks.

Concerning cold dark matter (CDM) search, the low background anticipated for GENIUS would, for the first time ever, allow to cover a significant part of the MSSM neutralino parameter space, making GENIUS competitive to LHC in SUSY discovery. If GENIUS could find SUSY CDM it would confirm that R-parity must be conserved exactly. GENIUS will thus be a major tool for future non-accelerator particle physics.
