Measurement of the forward-backward asymmetries of e(+)e(-)-> Z -> b(b)over-bar and e(+)e(-)-> Z -> c(c)over-bar using prompt leptons

Abstract:

The forward-backward asymmetries of the processes e+e - → Z → bb̄ and e+e- → Z → cc̄ were measured from a sample of hadronic Z decays collected by the DELPHI experiment between 1993 and 1995. Enriched samples of bb̄ and cc̄ events were obtained using lifetime information. The tagging of and and c quarks in these samples was based on the semileptonic decay channels b/c → X + μ and b/c → X + e combined with charge flow information from the hemisphere opposite to the lepton. Combining the AFBbb̄...
