1  AAD 2023AG based on 139 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 13 TeV. Pair production of vector-like top or ${{\mathit b}^{\,'}}$ is seached for in the mode 1${{\mathit \ell}}$ + ${}\geq{}$4j(${}\geq{}$1b-tagged) + $\not E_T$. The data are consistent with the SM background predictions and limits are obtained for different branching ratios.
2  SIRUNYAN 2019T based on 35.9 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 13 TeV. Signals are searched in the final states of ${{\mathit t}^{\,'}}$ pair production, with same-sign leptons (which come from a ${{\mathit t}^{\,'}}$ decay) or a single lepton (which comes from a ${{\mathit W}}$ out of 4${{\mathit W}}$s), along with jets, and no excess over the SM expectation is found.
3  AABOUD 2018CE based on 36.1 fb${}^{-1}$ of proton-proton data taken at $\sqrt {s }$ = 13 TeV. Events including a same-sign lepton pair are used. The limit is for the pair-produced vector-like ${{\mathit t}^{\,'}}$. With single ${{\mathit t}^{\,'}}$ production included, assuming ${{\mathit t}^{\,'}}{{\mathit t}}{{\mathit W}}$ coupling of one, the limit is ${\mathit m}_{{{\mathit t}^{\,'}}}$ $>$ 1.6 TeV.
4  SIRUNYAN 2017J based on 2.3 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 13 TeV. Signals are searched in the final states of ${{\mathit t}^{\,'}}$ pair production, with same-sign leptons (which come from a ${{\mathit t}^{\,'}}$ decay) or a single lepton (which comes from a ${{\mathit W}}$ out of 4${{\mathit W}}$s), along with jets, and no excess over the SM expectation is found.
5  AAD 2015BY based on 20.3 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 8 TeV. Limit on ${{\mathit t}^{\,'}{(5/3)}}$ in pair and single production assuming its coupling to ${{\mathit W}}{{\mathit t}}$ is equal to one. Used events containing ${}\geq{}2{{\mathit \ell}}$ + $\not E_T$ + ${}\geq{}$2j (${}\geq{}$1 ${{\mathit b}}$) and including a same-sign lepton pair.
6  AAD 2015Z based on 20.3 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 8 TeV. Used events with ${{\mathit \ell}}$ + $\not E_T$ + ${}\geq{}$6j (${}\geq{}$1 ${{\mathit b}}$) and at least one pair of jets from weak boson decay, sensitive to the final state ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit W}^{+}}{{\mathit W}^{-}}{{\mathit W}^{+}}{{\mathit W}^{-}}$.
7  CHATRCHYAN 2014T based on 19.5 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 8 TeV. Non-observation of anomaly in ${{\mathit H}_{{{T}}}}$ distribution in the same-sign dilepton events leads to the limit when pair produced ${{\mathit t}^{\,'}{(5/3)}}$ quark decays exclusively into ${{\mathit t}}$ and ${{\mathit W}^{+}}$, resulting in the final state with ${{\mathit b}}{{\overline{\mathit b}}}{{\mathit W}^{+}}{{\mathit W}^{-}}{{\mathit W}^{+}}{{\mathit W}^{-}}$.
8  AABOUD 2018AW based on 36.1 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 13 TeV. Limit on ${{\mathit t}^{\,'}{(5/3)}}$ in pair production assuming its coupling to ${{\mathit W}}{{\mathit t}}$ is equal to one. Lepton-plus-jets final state is used, characterized by ${{\mathit \ell}}$ + $\not E_T$ + jets (${}\geq{}$1 ${{\mathit b}}$-tagged).
