Technical aspects and dark matter searches

R. Bernabei, P. Belli, F. Cappella +12

A variety of detectors has been proposed for dark matter direct detection, but most of them -- by the fact -- are still at R&D stage. In many cases, it is claimed that the lack of…

Investigating pseudoscalar and scalar dark matter

R. Bernabei, P. Belli, F. Montecchia +10

In this paper another class of Dark Matter candidate particles: the pseudoscalar and scalar light bosonic candidates, is discussed. Particular care is devoted to the study of the p…

Half-life measurements of Po with thorium-loaded liquid scintillator

P. Belli, R. Bernabei, R. S. Boiko +11

Precise measurement of half-life of Po (one of the daughter nuclides in radioactive chain of Th) was realized by means of liquid scintillator based on toluene doped…
