Search for the neutral current top quark decay t -> Zc using the ratio of Z-boson+4 jets to W-boson+4 jets production

Abstract:

We have used the Collider Detector at Fermilab (CDF-II) to search for the flavor-changing neutral-current (FCNC) top-quark decay t→Zc using a technique employing ratios of W and Z production, measured in pp̄ data corresponding to an integrated luminosity of 1.52fb-1. The analysis uses a comparison of two decay chains, pp̄→tt̄→WbWb→νbjjb and pp̄→tt̄→ZcWb→cjjb, to cancel systematic uncertainties in acceptance, efficiency, and luminosity. We validate the modeling of acceptance and efficiency for...
