A particular kind of quintessence is considered, with equation of motion pQ/ρQ = −1, corresponding to a cosmological term with time-dependence Λ(t) = Λ(t0)(R(t0)/R(t)) P which we examine initially for 0 ≤ P < 3. Energy conservation is imposed, as is consistency with big-bang nucleosynthesis, and the range of allowed P is thereby much restricted to 0 ≤ P < 0.2. The position of the first Doppler ...

GENIUS is a proposal for a large volume detector to search for rare events. An array of 40–400 ’naked’ HPGe detectors will be operated in a tank filled with ultrapure liquid nitrogen. After a description of performed technical studies of detector operation in liquid nitrogen and of Monte Carlo simulations of expected background components, the potential of GENIUS for detecting WIMP dark matter,...
