Since april 1999, the KLOE experiment at DAFNE has collected about 200 inverse pb of data, produced in electron-positron collision at the c.m. energy of 1020 MeV, the mass of the phi meson. These data have been used for detailed studies on…
The original plan of a vigorous program of frontier physics at LNF, based on the phi-factory DAFNE with the KLOE detector, has not yet reached its major aim in the study of discrete symmetries in the neutral kaon system. It has however led…
The phi-factory DAPHNE offers a possibility to select pure kaon beams, charged and neutral ones. In particular, neutral kaons from phi->KS KL are produced in pairs and the detection of a KS (KL) tags the presence of a KL (KS). This allows…
The KLOE detector at the DA$\Phi$NE $\phi$-factory has been operating in two periods from 2001 to 2006 and from 2014 to 2018 collecting a large sample of $\phi$-meson decays. This allowed to perform precision measurements and studies of…
