Search for flavor-changing neutral current decays of the top quark in p(p)over-bar collisions at root s = 1.8 TeV

Abstract:
We search for the flavor-changing neutral current decays of the top quark t → qy and t → qZ (here q represents the c and u quarks) in pp collisions at √ s = 1.8 TeV. We use a dataset (∫ dt ∼ 110 pb-1) collected during the 1992-1995 run of the Collider Detector at Fermilab. We set 95% confidence level limits on the branching fractions B(t → qy) < 3.2% and B(t → qZ) < 33%, consistent with the standard model.
