Direct searches for dark matter
In the last decade considerable additional evidence has been gathered supporting the hypothesis that at least 90% of the mass in the universe is dark: it does not emit or absorb any form of electromagnetic radiation. Understanding this dark matter has become one of the more central problems in astronomy and cosmology. Once a subject of controversy among astronomers, its existence is now well es...
متن کاملScintillation efficiency of nuclear recoils in a CaF2(Eu) crystal for dark matter search
The scintillation efficiency (quenching factor) of fluorine and calcium nuclei recoiling in a CaF2(Eu) crystal was measured in an energy region relevant to dark matter searches. The recoiling nuclei were obtained via the 19F(n,n’) and 40Ca(n,n’) reactions, where the neutron beam was provided via the d(d,n)3He reaction. The quenching factor of F and Ca nuclei in the CaF2(Eu) crystal was found to...

متن کاملExperimental Searches for Dark Matter
There is now an enormously rich variety of experimental techniques being brought to bear on experimental searches for dark matter, covering a wide range of suggested forms for it. The existence of "dark matter", in some form or other, is inferred from a number of relatively simple observations and the problem has been known for over half a century. To explain "dark matter" is one of the foremos...
متن کاملDark Matter Searches
I'll start with a summary of the relevant evidence for cold dark matter from astrophysics and cosmology. The Standard Model of subnuclear physics does not have any dark matter particle, but its simplest extensions, the SUSY models, do have a very apt candidate, the neutralino. I will then briefly summarise the status and the expectations for the next years of indirect searches both with earth-b...
