Measurement of Direct CP Violation by NA48

High Energy Physics - Phenomenology 2017-08-23 v1

Abstract

The NA48 experiment at the CERN SPS aims to search for direct CP violation in the K0K^0 system through the measurement of Re(ϵ/ϵ){\rm Re}(\epsilon'/ \epsilon) with high accuracy. In 1999 the NA48 collaboration has published its first measuremen based on 1997 data. A new result, based on 1998 and 1999 data, is presented in this article. The result, combined with 1997 data, Re(ϵ/ϵ)=(15.3±2.6)×104{\rm Re}(\epsilon'/\epsilon) = (15.3 \pm 2.6)\times 10^{-4}, contributes to the precise determination of the size of direct CP violation.
