Ko","submitted_at":"2018-07-17T22:52:40Z","abstract_excerpt":"The search for singlet fermion dark matter at high-energy colliders is commonly analyzed with a singlet scalar mediator, which however violates the standard model (SM) gauge invariance, renormalizability and unitarity. These problems can be cured by introducing a mixing between the singlet scalar $s$ and the SM Higgs boson $h$. Thus one has to consider two scalar mediators $h_1$ and $h_2$, where $h_1$ is identified as the discovered 125 GeV Higgs boson. As a specific example, we consider the dark matter (DM) search in the $t \\bar{t} + E_{T}^{\\text{miss}}$ channel.
