T-Odd Anomalous Interactions of the Top-Quark at the Large Hadron Collider

Abstract

We study the effects of T-odd interactions of top-quark via the pair production of the top-quark in the semileptonic detection modes at the Large Hadron Collider by means of the T-odd observables constructed through the momenta of the observed decay products of the top (and anti-top)-quark for a wide range of CP-violating scale $\Lambda$ . Estimates on sensitivities of the coupling strength of such interactions for 13 TeV LHC energy with $\int \mathcal{L}dt=36.1\text{f}{\text{b}}^{-1}$ , $140\text{f}{\text{b}}^{-1}$ and for HL-LHC with 14 TeV energy with integrated luminosities of $0.3\text{a}{\text{b}}^{-1}$ , $1\text{a}{\text{b}}^{-1}$ , $2\text{a}{\text{b}}^{-1}$ , and $3\text{a}{\text{b}}^{-1}$ are also presented for $\Lambda$ ranging between $M_W$ and 2 TeV.
