Measurement of W-boson helicity fractions in top-quark decays using cos theta

Measurement of W-boson helicity fractions in top-quark decays using cos theta

Fully reconstructed t over(t, ̄) → W+ b W- over(b, ̄) → ℓ ν q over(q, ̄)′ b over(b, ̄) events are used to determine the fractions of right-handed (f+) and longitudinally polarized (f0) W bosons produced in top-quark decays. The helicity fractions are sensitive to the couplings and the Dirac structur...
