Findings

Distributions of physical observables depend on anomalous couplings.

Sensitivity estimates for tZ production via FCNC at the LHC are provided.

The model enables detailed studies of top quark FCNC processes.

Abstract

A UFO model describing general top quark Flavour Changing Neutral Currents is presented. We use it to study t$\gamma$, tH and tZ production via FCNCs anomalous couplings at the Large Hadron Collider, in particular how the distributions of physical observables depend on the anomalous couplings. A sensitivity study of the Large Hadron Collider experiments to tZ production via FCNC in its second stage of operation is also performed.
