Description

1 Higgs-Singlet Model (1HSM) is a minimal extension of the Standard Model with two physical scalar bosons. Top quark pair production in 1HSM is associated with large interference effects between loop-induced Higgs-mediated amplitudes and the QCD continuum background. I will talk about the research work on top quark pair production in 1HSM at NLO accuracy by Banfi et al. (arXiv: 2309.16759), and outline the main results. I will talk about the computation of the cross section of the top-quark pair production in the Higgs Effective Field Theory framework to make phenomenological predictions at the LHC.
