Abstract

This report summarizes the flavor tagging techniques developed at the CDF and D{\O}experiments. Flavor tagging involves identification of the B meson flavor atproduction, whether its constituent is a quark or an anti-quark. It is crucial for measuring the oscillation frequency of neutral B mesons, both in the B^0 and B_S system. The two experiments have developed their unique approaches to flavor tagging, using neural networks, and likelihood methods to disentangle tracks from $b$ decays from other tracks. This report discusses these techniques and the measurement of B^0 mixing, as a means to calibrate the taggers.
