New Measurements of CP Violation Parameters as Tests of CPT in K Meson Decay

Abstract

Using a technique which employs a pair of solid scintillator regenerators, the E773 collaboration has measured several CP violation parameters in K meson decay at Fermilab. We report new results for the phase of eta_+-, the K_L-K_S mass difference, the K_S lifetime, and the phase difference Arg(eta_00)-Arg(eta_+-) in K ->pi pi decay. In addition, we report a measurement of the magnitude and phase of eta_+-gamma in K ->pi+ pi- gamma decay. Our preliminary results are compared with theoretical expectations based on CPT symmetry.
