1  TUMASYAN 2021G based on 35.9 ${\mathrm {fb}}{}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 13 TeV. Events are selected by requiring 1${{\mathit \ell}}$ + 2jets(1${{\mathit b}}$ jet) final state. An average top mass of $172.13$ ${}^{+0.76}_{-0.77}$ GeV/c${}^{2}$ is obtained.
2  CHATRCHYAN 2017 based on 19.6 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 8 TeV and an average top mass of $172.84$ $\pm0.10~$(stat) GeV is obtained.
3  Based on 4.7 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 7 TeV and an average top mass of 172.5 GeV/c${}^{2}$.
4  Based on 8.7 fb${}^{-1}$ of ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV and an average top mass of 172.5 GeV/c${}^{2}$.
5  Based on 4.96 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 7 TeV. Based on the fitted ${\mathit m}_{{{\mathit t}}}$ for ${{\mathit \ell}^{+}}$ and ${{\mathit \ell}^{-}}$ events using the Ideogram method.
6  Based on a matrix-element method which employs 3.6 fb${}^{-1}$ in ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV.
7  Based on a template likelihood technique which employs 5.6 fb${}^{-1}$ in ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV.
8  Based on 1 fb${}^{-1}$ of data in ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV.
