摘要：

By using a neutral network classifier, we are able to identify simulated decays of the Z0 boson into bbBAR pairs with congruent-to 85% efficiency, and with a fraction of misidentified light quark decays of congruent-to 45%. The simulation takes into account the experimental inefficiencies and resolutions typical of a LEP detector, and makes use of the reconstruction of charged tracks only.
