Description
The KLOE-2 experiment at the INFN Laboratori Nazionali di Frascati has finished its data-taking campaign at the DAΦNE ϕ-factory with the collection of 5.5 fb$^{-1}$ of integrated luminosity. A peak luminosity of $2.4\times 10^{32} cm^{-2}s^{-1}$ and a maximum daily integrated of 14 pb$^{-1}$ were achieved with the crab waist scheme of beam collisions.
KLOE-2 represents the continuation of the KLOE experiment with a improved physics program mainly focused on the study of K$_S$, η rare decays as well as on kaon interferometry, test of discrete symmetries, and search for physics beyond the Standard Model. The collected data sample will allow to perform CPT symmetry and quantum coherence tests using entangled neutral kaons, studies of pseudoscalar mesons produced in γγ-physics collisions, and the search for signals of a hidden dark-matter sector, among the fields to be addressed.
The general purpose KLOE detector, composed by one of the biggest Drift Chamber ever built surrounded by a lead-scintillating fiber Electromagnetic Calorimeter among the best ones for energy and timing performance at low energies, undergone several upgrades including an Inner Tracker made of cylindrical GEMs, to improve vertex reconstruction capabilities near the interaction region, a tagging system for scattered electrons in γγ processes, and small angle calorimeters to inprove the acceptance for particles coming from the Interaction Point.
An overview of the KLOE-2 experiment will be given including present status and achievements together with physics plans.
