Neutral B Flavor Tagging for the Measurement of Mixing-induced CP Violation at Belle

arXiv:hep-ex/0403022 · doi:10.1016/j.nima.2004.06.159

Abstract

We describe a flavor tagging algorithm used in measurements of the CP violation parameter sin2phi_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 %.
