Pair production of the vectorlike top partner at future muon collider

Motivated by the recent interests in future high-energy muon colliders, we study the search potential of heavy singlet vectorlike top partner (VLQ-T) through the s-channel process μ+μ−→TT¯ at such facilities with s=6 TeV. We focus on the final signals via the T→Wb decay channel where one of the W bo...

Zusammenfassung:Motivated by the recent interests in future high-energy muon colliders, we study the search potential of heavy singlet vectorlike top partner (VLQ-T) through the s-channel process μ+μ−→TT¯ at such facilities with s=6 TeV. We focus on the final signals via the T→Wb decay channel where one of the W bosons decays leptonically and the other decays hadronically. By carrying out a full simulation for the signals and the relevant Standard Model backgrounds, the 2σ exclusion limit and 5σ discovery prospects are, respectively, obtained on the VLQ-T mass and the branching ratio of T→Wb. The numerical results show that the future high-energy muon collider will be a promising hunting ground for such new particles.
