dc.descriptionInterference between CKM-favored b --> c ubar d and doubly-CKM-suppressed bbar --> ubar c dbar 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 B0 B0bar 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 ~2% or less. The time-dependent analysis of D*pi, proposed for measuring sin(2 beta + gamma), must incorporate possible tag- side interference, which could produce asymmetries as large signal asymmetry.
