“…• In the single-produced process: (1) For the T → tH or T → tZ channel, the ATLAS collaboration performed a search and presented that the singlet T quark mass below 1.8(1.6) TeV was excluded for the universal coupling strength κ values In phenomenology, the studies of VLT have been performed extensively in general decay modes (W b, tZ, tH) [13][14][15][16][17][18][19][20][21][22] or some exotic channels [23][24][25][26][27]. Especially, the VLT can be probed at the LHC by the same-sign dilepton signature [28][29][30].…”

Based on a simplified model including a singlet vector-like top quark T with charge |Q| = 2/3, we analyze the prospects of observing T via the single T production in the tZ channel with Z decaying to neutrinos at the hadron-hadron colliders. This simplified model only includes two free parameters, the coupling constant g * and the T quark mass m T . To investigate the observability of the single T production, we perform a detailed background analysis and detector simulation for the collision energies 14 TeV, 27 TeV, and 100 TeV. We scan the g * − m T parameter space and show the exclusion and discovery capabilities on the T quark with the highest integrated luminosity designed at these colliders. Moreover, the limits from the narrowwidth approximation and electroweak precision observables are considered.

Based on a simplified model including a singlet vector-like top quark $T$ with charge |Q|=$2/3$, we analyze the prospects of observing $T$ via the single $T$ production in the $tZ$ channel with $Z$ decaying to neutrinos at the hadron-hadron colliders. This simplified model only includes two free parameters, the coupling constant $g^*$ and the $T$ quark mass $m_T$. In order to investigate the observability of the single $T$ production, we make a detailed background analysis and detector simulation for the collision energy 14~TeV, 27~TeV and 100~TeV. We scan the $g^*-m_T$ parameter space and show the exclusion and discovery capabilities on the $T$ quark with the highest integrated luminosity designed at these colliders. Besides, the limits from the narrow-width approximation and electroweak precision observables are also been considered.
