AAD 2016AV based on 20.3 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 8 TeV. No significant excess over SM expectation is found in the search for a fully reconstructed vector-like ${{\mathit t}^{\,'}}$ in the mode ${{\mathit \ell}}$ + $\not E_T$ + ${}\geq{}2{{\mathit j}}$ (${}\geq{}1{{\mathit b}}$). A veto on massive large-radius jets is used to reject the ${{\mathit t}}{{\overline{\mathit t}}}$ background.

Based on 5.4 fb${}^{-1}$ of data in ppbar collisions at 1.96 TeV. ABAZOV 2011F looked for single production of ${{\mathit t}^{\,'}}$ via the ${{\mathit Z}}$ or ${{\mathit E}}$ coupling to the first generation up or down quarks, respectively. Model independent cross section limits for the single production processes ${{\mathit p}}$ ${{\overline{\mathit p}}}$ $\rightarrow$ ${{\mathit t}^{\,'}}{{\mathit q}}$ $\rightarrow$ ( ${{\mathit W}}{{\mathit d}}$ )${{\mathit q}}$, and ${{\mathit p}}$ ${{\overline{\mathit p}}}$ $\rightarrow$ ${{\mathit t}^{\,'}}{{\mathit q}}$ $\rightarrow$ ( ${{\mathit Z}}{{\mathit d}}$ )${{\mathit q}}$ are given in Figs. 3 and 4, respectively, and the mass limits are obtained for the model of ATRE 2009 with degenerate bi-doublets of vector-like quarks.
