Search for the flavor-changing neutral-current decay t→Zq in pp̄ collisions at s=1.96TeV

Abstract:

We report a search for the flavor-changing neutral-current decay of the top quark t→Zq (q=u, c) in pp̄ collisions at s=1.96TeV using a data sample corresponding to an integrated luminosity of 1.9fb-1 collected by the CDF II detector. This decay is strongly suppressed in the standard model and an observation of a signal at the Fermilab Tevatron would be an indication of physics beyond the standard model. Using Z+4 jet final state candidate events, with and without an identified bottom quark je...
