We study the flavor changing neutral current couplings of new heavy quarks through the models at the LHC. We calculate the cross sections for the signal and the corresponding standard model background processes. Considering the present limits on the mass of new heavy quarks and the boson, we performed an analysis to investigate the parameter space (mixing and mass) through different models. For FCNC mixing parameter and the mass  GeV and new heavy quark mass  GeV at the LHC with  TeV, we find the cross section for single production of new heavy quarks associated with top quarks as  fb,  fb,  fb, and  fb within the , , , and models, respectively. It is shown that the sensitivity would benefit from the flavor tagging.
