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,...

A very weakly coupled scalar field with mass m and initial vacuum expectation value V will provide enough mass to close the universe provided V ≃ (3 × 10 8 GeV)(100 GeV/m) 1/4. We discuss possible models in which such a field could arise. (a) Electronic address (internet): [email protected].

MACHe3 (MAtrix of Cells of superfluid 3 He) is a project of a new detector for direct Dark Matter (DM) search. A cell of superfluid 3 He has been developed and the idea of using a large number of such cells in a high granularity detector is proposed.This contribution presents, after a brief description of the superfluid 3 He cell, the simulation of the response of different matrix configuration...

Received ; accepted – 2 – ABSTRACT We have studied five seasons of OGLE-III data for eight SMC Be/X-ray pulsars for which no other survey data were available. We have determined orbital periods for four of these binary systems, one of which also shows nonradial pulsations. Optical identification of SMC X-2 is reconsidered, but no periods were found for either of the two possible candidates.
