A measurement of the forward-backward asymmetry of e+e−→bb by applying a jet charge algorithm to lifetime tagged events

The forward-backward asymmetry of$$e^ + e^ - \to Z^0 \to b\bar b$$ has been measured using approximately 2.15 million hadronicZ0 decays collected at the LEP e+e− collider with the OPAL detector. A lifetime tag technique was used to select an enriched$$b\bar b$$ event sample. The measurement of the$$b\bar b$$ asymmetry was then performed using a jet charge algorithm to determine the direction of the primary quark. Values …
