Helicity of the W boson in lepton + jets tt̄ events
- Abstract:
-
We examine properties of tt̄ candidate events in lepton + jets final states to establish the helicities of W bosons in t→W+b decays. Our analysis is based on a direct calculation of a probability density for each event to correspond to a tt̄ final state, as a function of the helicity of the W boson. Using the 125 events/pb of data collected by the DØ experiment at the Fermilab Tevatron pp̄ Collider at s=1.8 TeV, we obtain a longitudinal helicity fraction F0=0.56±0.31, consistent with the pred...
