DAFNE or DAΦNE (Double Annular Φ Factory for Nice Experiments), is an electron-positron collider at the INFN Frascati National Laboratory in Frascati, Italy. Since 1999 it has been colliding electrons and positrons at a center of mass energy of 1.02 GeV to create phi mesons (φ). 85% of these decay into kaons (K), whose physics is the subject of most of the experiments at DAFNE. There are five experiments at DAFNE: * KLOE (K LOng Experiment), which has been studying CP violation in kaon decays and rare kaon decays since 2000. This is the largest of DAFNE experiments. * FINUDA (FIsica NUcleare a DAFNE), studies the spectra and nonmesonic decays of hypernuclei containing Lambda baryons (Λ). The hypernuclei are produced by negatively charged kaons () striking a thin target. * DEAR (DAFNE Exotic Atoms Research experiment), determines scattering lengths in atoms made from a kaon and a proton or deuteron. * DAFNE Light Laboratory consists of 3 lines of synchrotron radiation emitted by DAFNE, a fourth is under construction. * SIDDHARTA (SIlicon Drift Detectors for Hadronic Atom Research by Timing Application), aims to improve the precision measurements of X-ray transitions in kaon atoms studied at DEAR. ==External links== * Homepage of the accelerator division of Frascati National Laboratory: (public (Italian) ), (technical ) 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「DAFNE」の詳細全文を読む スポンサード リンク
