Abstract

The full E731 data set is used to provide precise determinations of several parameters of the neutral kaon. We find the KS lifetime τS=(0. 8929±0.0016)×10-10 s, the KL-KS mass difference Δm=(0.5286±0.0028)×1010Latin small letter h with stroke s-1 the phase of η+-, Φ+-=42.4°±1.4°, and the phase difference between Φ00 and Φ+-, ΔΦ=-1.6°±1.2°. Comparisons with previous experiments and with CPT symmetry are given.
