Auditorium M. Vivargent (LAPP)

The upgraded DAPHNE collider in Frascati is now capable to reach peak luminosities around 5x10**32 cm-2s-1 and to deliver up to 15 pb-1/day of phi mesons. The KLOE detector is being upgraded with an inner tracker, two low angle calorimeters and a gamma-gamma tagger, and will start a data taking campaing in two steps: the first will start early in 2010, with minimal upgrades, aiming to collect around 5 fb-1; the second is foreseen for the late 2011, after the full upgrade installation, and will aim to collect a data sample of at least 20 fb-1. This seminar wil briefly describe both the accelerator and the detector upgrades, and will then review the rich physics program that KLOE-2 will be able to investigate: kaon physics, eta and eta' physics, light hadron spectroscopy, gamma-gamma physics, hadronic cross section, low energy dark matter, fundamental tests of quantum mechanics and CPT violation.
