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 Λ. Estimates on sensitivities of the coupling strength of such interactions for 13 TeV LHC energy with ∫Ldt=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 Λ ranging between MW and 2 TeV.
