1  SIRUNYAN 2020AI search for resonances decaying into dijets in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV. The limit above assumes ${{\mathit S}_{{{8gg}}}}$ coupling ${{\mathit k}_{{{s}}}^{2}}$ = 1/2.
2  SIRUNYAN 2018BO search for color octet scalar boson produced through gluon fusion process in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV. The limit above assumes ${{\mathit S}_{{{8gg}}}}$ coupling ${{\mathit k}_{{{s}}}^{2}}$ = 1/2.
3  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 ${\mathit m}_{{{\mathit \Theta}^{0}}}$).
4  AAD 2013K search for pair production of color-octet scalar particles in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV. Cross section limits are interpreted as mass limits on scalar partners of a Dirac gluino.
