Abstract
The forward-backward asymmetries for the processes e+e−cc and e+e−bb at theZ resonance are measured using identifiedD *± mesons. In 905,000 selected hadronic events, taken in 1991 and 1992 with the DEL-PHI detector at LEP, 4757D *+ Constraining theb asymmetry to the value measured by DELPHI using independent analyses, the charm asymmetry is determined to be: AFBcconst=00680027(stat)0011(sys) . This result corresponds to an effective electroweak mixing angle measured using charm quark events of: sin2efflept=0230700062(stat)00026(sys)I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
