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 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 the sensitivities of the coupling strength of such interactions for 13 TeV LHC energy with $\int \mathcal{L}dt$ = 36.1 fb${}^{-1}$, 140 fb${}^{-1}$ and for HL-LHC with 14 TeV energy with integrated luminosities of 0.3 ab${}^{-1}$, 1 ab${}^{-1}$, 2 ab${}^{-1}$ and 3 ab${}^{-1}$ are also presented for $\Lambda$ ranging between $M_W$ and 2 TeV.
