翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク European Underground Rare Event Calorimeter Array ： ウィキペディア英語版 European Underground Rare Event Calorimeter Array The European Underground Rare Event Calorimeter Array (EURECA) is a planned dark matter search experiment using cryogenic detectors and an absorber mass of up to 1 tonne. The project will be built in the Modane Underground Laboratory and will bring together researchers working on the CRESST and EDELWEISS experiments.〔 H. Kraus et al. (2006) 'EURECA – the European future of cryogenic dark matter searches' Journal of Physics: Conference Series 39 139-141. .〕〔H. Kraus et al. (2007) 'EURECA – the European Future of Dark Matter Searches with Cryogenic Detectors' Nuclear Physics B (Proc. Suppl.) 173 168-171 .〕 EURECA featured prominently in the ASPERA road map of Astroparticle Physics experiments in Europe.〔( Astroparticle Physics, the European Strategy ) (ASPERA Roadmap).〕 ==Dark matter== (詳細はunsolved problems in modern science. There is considerable evidence from astronomy and cosmology that a significant fraction of the mass of the Universe, and of galaxies is made up of non-luminous material. The nature of dark matter is currently unknown. However a popular hypothesis is that it consists of Weakly Interacting Massive Particles (WIMPs), particles with a large mass, but which only interact with ordinary matter through the weak nuclear force, so the majority that pass through the Earth do not hit a single atom. The aim of dark matter search experiments such as EURECA is to test this hypothesis by searching for WIMP dark matter interactions. WIMPs are predicted to exist by supersymmetry theory, which predicts a wide range of scattering cross-sections down to 10−10pb, corresponding to an interaction rate of ~1 event per year in a 1 tonne detector.〔R. Trotta, R. Ruiz de Austri and L. Roszkowski, (2007) 'Prospects for direct dark matter detection in the constrained MSSM' New Astronomy Reviews 51 316 〕 Existing experiments such as CRESST and EDELWEISS have already ruled out higher interaction rates, but EURECA will search down to this lower limit. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「European Underground Rare Event Calorimeter Array」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
