Abstract: As an extension of the standard model, the introduction of Vector Like Quarks provides a possible solution to various unsolved issues, such as the hierarchy problem. We present a search for the single production of the vector-like top quark T', in the decay channel T'->H (->WW)top, in the final state with two opposite sign leptons. In the signature targeted by this analysis, the Higgs boson decays into two W bosons which subsequently decay into two leptons and two neutrinos, while the top quark is reconstructed in the fully hadronic final state. The poster presents a cut-based event selection strategy designed with an MC study, followed by a T’ reconstruction method based on the Chi2 sorting algorithm and neutrino kinematic approximations. The current study is optimized for the di-muon channel at a T' mass of 700 GeV.
