摘要：

Interference between Cabibbo-Kobayashi-Maskawa (CKM) favored b-->c (u) over bard and doubly-CKM-suppressed (b) over bar -->(u) over barc (d) over bar amplitudes in final states used for B-flavor tagging gives deviations from the standard time evolution assumed in CP-violation measurements at B factories producing coherent B-0(B) over bar (0) pairs. We evaluate these deviations for the standard time-dependent CP-violation measurements, the uncertainties they introduce in the measured quantities, and give suggestions for minimizing them. The uncertainty in the measured CP asymmetry for CP eigenstates is approximate to2% or less. The time-dependent analysis of D*pi, proposed for measuring sin(2beta+gamma), must incorporate possible tag-side interference, which could produce asymmetries as large as the expected signal asymmetry.
