Description

We study the anomalous FCNC tqγ and tqg couplings via pp → Wbγ + 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 λ and ζ couplings but also branching ratios of t → qγ and t → qg decay channels. We find that the sensitivity to the branching ratio of t → qγ channel is three order better than the available LHC experimental limits, and it is comparable for the branching ratio of the t → qg decay channel with an integrated luminosity of 10 ab-1 at 2σ significance level.
