Latest Results on Kaon Physics from the NA48 Experiment

Abstract

The NA48 experiment, conceived primarily to look for direct CP violation in neutral kaon decays, has recently published the so far most precise determination of the epsilon'/epsilon parameter. After reviewing shortly this result, we report on the 2001 data-taking, which concluded the epsilon' program by collecting a substantial amount of data with different beam intensity conditions. We also present new precision measurements of the K0 and eta masses and of the K-short lifetime, that provide consistency checks of our analysis. Finally, the prospects for the future experimental program are discussed.
