Abstract
The scalar color octet contribution to the resonance t t -pair production at the LHC is calculated and analyzed with account of the one loop effective two gluon vertex. From current LHC data on total cross section and invariant mass spectrum of t t production we found the m F 2 − sin β -plane exclusion regions.
