Description
We consider the top-pair production through pp annihilation, followed by the semileptonic decay of the top-quark. We study the new physics contributions to the Wtb vertex at the Large Hadron Collider. In particular, we estimate the limits on anomalous couplings for the pre-existing data of 13 TeV LHC energy with integrated luminosities of 36.1 fb^{-1} and 140 fb^{-1}. Prediction of limits on anomalous couplings for future hadron colliders, namely, HL-LHC, HE-LHC and FCC-hh is also discussed at the proposed luminosities. In addition, we construct CP-violating asymmetries to study the CP-violating effects arising due to Wtb vertex and give estimates on the sensitivity to CP-violating anomalous couplings.
