KLOE-2, how to do fundamental physics at a low energy facility
Professor Fabio Bossi (INFN, Frascati)

The KLOE experiment has completed its first data taking phase in March 2006 at the DAFNE phi-factory of the Laboratori Nazionali dell ′ INFN in Frascati, Italy.
The analysis of the acquired 2.5 fb-1 has produced several important results, including the most precise test for unitarity of the CKM matrix, a test for the conservation of the leptonic number in charged kaon decays, as well as for the conservation of CPT symmetry with consequences for quantum gravity inspired models. In the field of hadronic physics, besides several measurements of rare KS, eta and eta ′ decays, KLOE has produced a precise determination of the hadronic cross section at low energy which is relevant for the calculation of the contribution to the muon magnetic anomaly.
In the course of the last two years the DAFNE team has been able to increase the luminosity of the machine by a factor about 3. KLOE has therefore re-entered the beam line, and is starting a new data taking campaing, under the name of KLOE-2, with the purpose of maximally exploiting the physics potentials of the new machine.
