8  AAD 2016W search for a new resonance decaying to a pair of ${{\mathit b}}$ and ${{\mathit B}_{{{H}}}}$ in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV. The vector-like quark ${{\mathit B}_{{{H}}}}$ is assumed to decay to . See their Fig. 3 and Fig. 4 for limits on $\sigma \cdot{}\mathit B$.
9  KHACHATRYAN 2016E search for KK gluon decaying to ${{\mathit t}}{{\overline{\mathit t}}}$ in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV.
10  KHACHATRYAN 2015AV search for pair productions of neutral color-octet weak-triplet scalar particles (${{\mathit \Theta}^{0}}$), decaying to ${{\mathit b}}{{\overline{\mathit b}}}$, ${{\mathit Z}}{{\mathit g}}$ or ${{\mathit \gamma}}{{\mathit g}}$, in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV. The ${{\mathit \Theta}^{0}}$ particle is often predicted in coloron (${{\mathit G}^{\,'}}$, color-octet gauge boson) models and appear in the ${{\mathit p}}{{\mathit p}}$ collisions through ${{\mathit G}^{\,'}}$ $\rightarrow$ ${{\mathit \Theta}^{0}}{{\mathit \Theta}^{0}}$ decays. Assuming B( ${{\mathit \Theta}^{0}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}$) = 0.5, they give limits ${\mathit m}_{{{\mathit \Theta}^{0}}}$ $>$ 623 GeV (426 GeV) for ${\mathit m}_{{{\mathit G}^{\,'}}}$ = 2.3 ${\mathit m}_{{{\mathit \Theta}^{0}}}$ (${\mathit m}_{{{\mathit G}^{\,'}}}$ = 5 ${\mathit m}_{{{\mathit \Theta}^{0}}}$).
11  AALTONEN 2013R search for new resonance decaying to ${{\mathit \sigma}}{{\mathit \sigma}}$, with hypothetical strongly interacting ${{\mathit \sigma}}$ particle subsequently decaying to 2 jets, in ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV, using data corresponding to an integrated luminosity of 6.6 fb${}^{-1}$. For 50 GeV $<$ ${\mathit m}_{{{\mathit \sigma}}}$ $<$ ${\mathit m}_{{{\mathit g}_{{{A}}}}}$/2, axigluons in mass range $150 - 400$ GeV are excluded.
12  CHATRCHYAN 2013A search for new resonance decaying to dijets in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV.
13  CHATRCHYAN 2013AS search for new resonance decaying to dijets in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV.

15  ABAZOV 2012R search for massive color octet vector particle decaying to ${{\mathit t}}{{\overline{\mathit t}}}$. The quoted limit assumes ${{\mathit g}_{{{A}}}}$ couplings with light quarks are suppressed by 0.2.
16  CHATRCHYAN 2011Y search for new resonance decaying to dijets in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }~=~7~$TeV.
17  AALTONEN 2010L search for massive color octet non-chiral vector particle decaying into ${{\mathit t}}{{\overline{\mathit t}}}$ pair with mass in the range 400 GeV $<$ M $<$ 800 GeV. See their Fig.$~$6 for limit in the mass-coupling plane.
18  KHACHATRYAN 2010 search for new resonance decaying to dijets in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }~=~7~$TeV.
19  AALTONEN 2009AC search for new narrow resonance decaying to dijets.
20  CHOUDHURY 2007 limit is from the ${{\mathit t}}{{\overline{\mathit t}}}$ production cross section measured at CDF.
21  DONCHESKI 1998 compare $\alpha _{\mathit s}$ derived from low-energy data and that from $\Gamma\mathrm {( {{\mathit Z}} \rightarrow hadrons)}/\Gamma\mathrm {( {{\mathit Z}} \rightarrow leptons)}$.
22  ABE 1997G search for new particle decaying to dijets.
23  ABE 1995N assume axigluons decaying to quarks in the Standard Model only.
24  ABE 1993G assume $\Gamma\mathrm {({{\mathit g}_{{{A}}}})}$ = $\mathit N{{\mathit \alpha}_{{{s}}}}{\mathit m}_{{{\mathit g}_{{{A}}}}}$/6 with $\mathit N$ = 10.
25  CUYPERS 1991 compare $\alpha _{\mathit s}$ measured in ${{\mathit \Upsilon}}$ decay and that from $\mathit R$ at PEP/PETRA energies.
26  ABE 1990H assumes $\Gamma\mathrm {({{\mathit g}_{{{A}}}})}$ = $\mathit N{{\mathit \alpha}_{{{s}}}}{\mathit m}_{{{\mathit g}_{{{A}}}}}$/6 with $\mathit N$ = 5$~(\Gamma\mathrm {({{\mathit g}_{{{A}}}})}$ = 0.09${\mathit m}_{{{\mathit g}_{{{A}}}}}$). For $\mathit N$ = 10, the excluded region is reduced to 120$-$150 GeV.
27  ROBINETT 1989 result demands partial-wave unitarity of $\mathit J = 0$ ${\mathit {\mathit t}}$ ${\mathit {\overline{\mathit t}}}$ $\rightarrow$ ${\mathit {\mathit t}}$ ${\mathit {\overline{\mathit t}}}$ scattering amplitude and derives a limit ${\mathit m}_{{{\mathit g}_{{{A}}}}}$ $>$ $0.5$ ${\mathit m}_{{{\mathit t}}}$. Assumes ${\mathit m}_{{{\mathit t}}}$ $>$ 56 GeV.
28  ALBAJAR 1988B result is from the nonobservation of a peak in two-jet invariant mass distribution. $\Gamma\mathrm {({{\mathit g}_{{{A}}}})}$ $<$ $0.4$ ${\mathit m}_{{{\mathit g}_{{{A}}}}}$ assumed. See also BAGGER 1988.
29  CUYPERS 1988 requires $\Gamma\mathrm {( {{\mathit \Upsilon}} \rightarrow {{\mathit g}} {{\mathit g}_{{{A}}}})}<\Gamma\mathrm {( {{\mathit \Upsilon}} \rightarrow {{\mathit g}} {{\mathit g}} {{\mathit g}})}$. A similar result is obtained by DONCHESKI 1988.
30  DONCHESKI 1988B requires $\Gamma\mathrm {( {{\mathit \Upsilon}} \rightarrow {{\mathit g}} {{\mathit q}} {{\overline{\mathit q}}})}/\Gamma\mathrm {( {{\mathit \Upsilon}} \rightarrow {{\mathit g}} {{\mathit g}} {{\mathit g}})}$ $<$ $0.25$, where the former decay proceeds via axigluon exchange. A more conservative estimate of $<$ $0.5$ leads to ${\mathit m}_{{{\mathit g}_{{{A}}}}}$ $>$ 21 GeV.
