Abstract

We study the anomalous FCNC tq and tqg couplings via ppWb+X signal process including realistic detector effects for both leptonic and hadronic decay channels of the W boson at 100 TeV FCC-hh. The relevant backgrounds are considered in the cut based analysis to obtain not only limits on the anomalous and couplings but also branching ratios of tq and tqg decay channels. We find that the sensitivity to the branching ratio of tq channel is three order better than the available LHC experimental limits, and it is comparable for the branching ratio of the tqg decay channel with an integrated luminosity of 10 ab-1 at 2 sigma significance level.
