1  AABOUD 2017AK limit is from dijet angular distribution in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV. ${{\mathit u}}$, ${{\mathit d}}$, and ${{\mathit s}}$ quarks are assumed to be composite.
2  AABOUD 2018AV obtain limit on ${{\mathit t}_{{R}}}$ compositeness 2${{\mathit \pi}}/{{\mathit \Lambda}_{{RR}}^{2}}$ $<$ 1.6 TeV${}^{-2}$ at 95$\%$ CL from ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit t}}{{\overline{\mathit t}}}$ production in the ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV.
3  SIRUNYAN 2018DD limit is from dijet angular distribution in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV.
4  SIRUNYAN 2017F limit is from dijet angular cross sections in ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. All quarks are assumed to be composite.
5  AAD 2016S limit is from dijet angular selections in ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. ${{\mathit u}}$, ${{\mathit d}}$, and ${{\mathit s}}$ quarks are assumed to be composite.
6  AAD 2015AR obtain limit on the ${{\mathit t}_{{R}}}$ compositeness 2$\pi /{{\mathit \Lambda}_{{RR}}^{2}}$ $<$ 6.6 TeV${}^{-2}$ at 95$\%$ CL from the ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit t}}{{\overline{\mathit t}}}$ production in the ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV.
7  AAD 2015BY obtain limit on the ${{\mathit t}_{{R}}}$ compositeness 2$\pi /{{\mathit \Lambda}}{}^{2}_{RR}$ $<$ 15.1 TeV${}^{-2}$ at 95$\%$ CL from the ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit t}}{{\overline{\mathit t}}}$ production in the ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV.
8  AAD 2015L limit is from dijet angular distribution in ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV. ${{\mathit u}}$, ${{\mathit d}}$, and ${{\mathit s}}$ quarks are assumed to be composite.
9  KHACHATRYAN 2015J limit is from dijet angular distribution in ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV. ${{\mathit u}}$, ${{\mathit d}}$, ${{\mathit s}}$, ${{\mathit c}}$, and ${{\mathit b}}$ quarks are assumed to be composite.
10  FABBRICHESI 2014 obtain bounds on chromoelectric and chromomagnetic form factors of the top-quark using ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit t}}{{\overline{\mathit t}}}$ and ${{\mathit p}}$ ${{\overline{\mathit p}}}$ $\rightarrow$ ${{\mathit t}}{{\overline{\mathit t}}}$ cross sections. The quoted limit on the ${{\mathit q}}{{\overline{\mathit q}}}{{\mathit t}}{{\overline{\mathit t}}}$ contact interaction is derived from their bound on the chromoelectric form factor.
