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(eta₀0)-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.
