Abstract

The difference between the quantity \(\tilde \in \) induced by box diagram and the experimentally measured value of ɛ is determined and used to obtain the value of ∈ with high precision. Present-day knowledge of CKM matrix elements (including B-factory data) allows us to obtain from the SM expression for \(\tilde \in \) the value of parameter B K : B K =0.89±0.16. It turns out to be very close to the result of vacuum insertion, B K =1.
