We search for the flavor-changing neutral current decays of the top quark t --> q gamma and t --> qZ (here q represents the c and u quarks) in (p) over bar p collisions at root s = 1.8 TeV. We use a dataset (integral L dt similar to 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 --> q gamma) < 3.2% and B(t --> qZ) < 33%, consistent with the standard model.

Abstract
We search for the flavor-changing neutral current decays of the top quark t --> q gamma and t --> qZ (here q represents the c and u quarks) in (p) over bar p collisions at root s = 1.8 TeV. We use a dataset (integral L dt similar to 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 --> q gamma) < 3.2% and B(t --> qZ) < 33%, consistent with the standard model.File in questo prodotto:
