讨论了最近提出的双β衰变和暗物质实验GENIUS的物理势。该实验将允许探测中微子质量低至10−（2-3）eV。GENIUS将测试中微子质量矩阵的结构，因此隐含的中微子振荡参数在灵敏度上与提议的最佳专用地面中微子振荡实验相当或上级。如果达到10-3eV的水平，GENIUS甚至可以测试太阳中微子问题的大角度MSW解决方案。即使在第一阶段，GENIUS也将确认或排除简并或倒置中微子质量的情况，这在文献中已经被广泛讨论，作为对当前有限中微子质量暗示的可能解决方案，并且还测试了大气中微子问题的νe Participate νμ假设。GENIUS将有助于在类似于或上级于LHC的尺度上寻找违反超对称性的R宇称和右手W玻色子。此外，GENIUS将大大改善目前0νββ衰变对R宇称守恒超对称性和细夸克的搜索。在冷暗物质（CDM）搜索方面，GENIUS预期的低背景将有史以来第一次允许覆盖完整的MSSM中性伴子参数空间，使GENIUS在超对称性发现方面与LHC竞争。如果GENIUS能找到SUSY CDM作为副产品，它将确认R-宇称必须精确守恒。因此，GENIUS将成为未来非加速器粒子物理学的主要工具。
The physics potential of GENIUS, a recently proposed double beta decay and dark matter experiment is discussed. 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 10-3eV 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 νe↔ νμhypothesis 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 0νββ 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 the complete MSSM neutralino parameter space, making GENIUS competitive to LHC in SUSY discovery. If GENIUS could find SUSY CDM as a by-product it would confirm that R-parity must be conserved exactly. GENIUS will thus be a major tool for future non-accelerator particle physics.
