Search for right-handed W bosons in top quark decay

Abstract:

We present a measurement of the fraction f+ of right-handed W bosons produced in top quark decays, based on a candidate sample of tt̄ events in the lepton+jets decay mode. These data correspond to an integrated luminosity of 230pb-1, collected by the D0 detector at the Fermilab Tevatron pp̄ Collider at s=1.96TeV. We use a constrained fit to reconstruct the kinematics of the tt̄ and decay products, which allows for the measurement of the leptonic decay angle θ* for each event. By comparing the...
