Description
The contributions to the cross sections ${ t\bar{t} t\bar{t}}$ and $t\bar{t}b\bar{b}$ production at the LHC from color scalar octets (scalar gluons) $F_a$ predicted by the minimal model with four color quark-lepton symmetry are calculated.
From current LHC data on total cross section of $ t\bar{t}t\bar{t}$ and $t\bar{t}b\bar{b}$ production we found the mass limits on color scalar octets $F_a$.
