TL;DR
This paper reports the latest results from the NA48 experiment at CERN, focusing on measurements of direct CP violation and rare kaon decays, including branching ratios and CP-violating parameters, based on data from 1998-1999.
Contribution
It provides new measurements of CP violation parameters and rare decay branching ratios, advancing understanding of CP violation in kaon decays.
Findings
Measurement of Re(e'/e) with combined 1998-1999 data
New results on branching ratio of KL->pi0gg
Updated A_v factor for KL->pi+pi-e+e- decay
Abstract
In this article the current status and latest results of the NA48 experiment at CERN are given. We present in more details the analysis performed for the Re(e'/e) measurement with the combined statistics accumulated during the 1998 and 1999 data periods. Reviewing the NA48 rare decay program, we select to underline the new results on the branching ratio and the A_v factor for the decay KL->pi0gg and the KL->pi+pi-e+e- CP violating decay. This article is the contribution to the Proceedings of the Lepton-Photon Conference held in Roma, July 23-29 2001.
