Abstract
The KLOE calorimeter is a fine lead-scintillating fiber sampling calorimeter. We describe in the following the calibration procedures and the calorimeter performances obtained after 3 years of data taking. We get an energy resolution for electromagnetic showers of 5.4%/ E (GeV) and a time resolution of 56 ps/ E (GeV) . We also present a measurement of efficiency for low-energy photons.

G. Amelino-Camelia, +101 more
TL;DR: In this paper, the authors discuss the recent theoretical development and experimental progress in kaon physics relevant for the Standard Model tests in the flavor sector, the sensitivity we can reach in probing CPT and Quantum Mechanics from time evolution of entangled-kaon states, the interest for improving on the present measurements of non-leptonic and radiative decays of kaons and eta/eta' mesons, and contribution to understand the nature of light scalar mesons.
