Descripción

CERN-LEP. ALEPH Collaboration. Measurement of the forward- backward asymmetry in Z --& gt; bbbar and Z --& gt; ccbar decays. Two methods are employed to select the quark asymmetries. The first uses high pt leptons to enrich the sample with b decays and the second fits the full pt range allowing both the b and c asymmetries to be measured.. These asymmetries correspond to the value of effective electroweak mixing angle, SIN2TW = 0.2262 +- 0.0053.
