摘要：
We describe a flavor tagging algorithm used in measurements of the CP violation parameter sin 2phi(1) at the Belle experiment. Efficiencies and wrong tag fractions are evaluated using flavor-specific B meson decays into hadronic and semileptonic modes. We achieve a total effective efficiency of 28.8 +/- 0.6%.
