KLOE

The KLOE -2experiment, which ended his data acquisition period  in the 30 March 2018,  was located on the DAFNE collider in Frascati, which is a e+ e storage ring at high luminosity (1033 cm-2 s-1) and energy around the Phi resonance (1020 MeV)

One of the main objectives of KLOE-2 collaboration is the study of  quantum interference phenomena of neutral K-mesons produced at DAFNE together with the very high precision study of the intrinsic properties of particles of matter (kaons) compared to those. The apparatus, optimized to detect charged and neutral decays of both KS and KL mesons,  was composed of a large-volume drift chamber surrounding the beam interaction region and an electromagnetic calorimeter. A superconducting coil with an iron return yoke was able to provide a longitudinal magnetic field, needed to measure the charged particle momentum.

Ended the data collection campaign, the Kloe-2 collaboration is now engaged in the analysis of the acquired data.

The two detectors HET (High Energy Tagger) realized by the KLOE-2 Tor Vergata group continue to be used as luminosity measurements detectors for DAFNE e+ e- beams.
