Abstract
- We study the anomalous FCNC $tq\gamma$ and $tqg$ couplings via $pp\to Wb\gamma+X$ signal process including realistic detector effects for both leptonic and hadronic decay channels of the W boson at 100 TeV FCC-hh. The relevant background are considered in the cut based analysis to obtain not only limits on the anomalous $\lambda$ and $\zeta$ couplings but also branching ratios of $t\to q\gamma$ and $t\to qg$ decay channels. We find that the sensitivity to the branching ratio of $t \to q \gamma$ channel is three order better than the available LHC experimental limits, and it is comparable for the branching ratio of the $t\to qg$ decay channel with an integrated luminosity of 10 ab$^{-1}$ at 2$\sigma$ significance level.<br />Comment: 18 pages, 7 figures, 4 tables, accepted version by Eur.
