Z DECAYS TO TOP QUARKS

Program Document ·
OSTI ID:1447766
Z decays to top quark pairs—if kinematically possible—will provide an accurate measurement of the top quark mass in e+e- collisions. We study various distributions of leptons and jets in the final state for semileptonic quark decays. Fragmentation and polarization effects are analyzed. In addition to large longitudinal and transverse polarizations, a small normal t-quark polarization is built up by γ,Z interference and perturbative QCD corrections. We comment also briefly on polarization effects in the $$t\bar{b}$$ decays of W bosons that are hadronically produced.
