Abstract

The best estimation of ϕ +− (the phase of the CP violation parameter η +−) and of Δm (the K L - K S mass difference) is obtained by averaging the results of different experiments, taking into account the different correlation, existing for most of the experiments, between the measurement of ϕ +− and Δm. Including the recent measurements, we obtain the average values 〈Δm〉 = (530.7 ± 1.3) × 10 7 ħ/s and 〈 ϕ +−〉 = 43.82° ± 0.63°. This value of ϕ +− is in good agreement with the superweak phase ϕ SW = 43.49° ± 0.08°.
