Tevatron potential for technicolor search with prompt photons

We perform a detailed study of the process of single color octet isoscalar ηT production at the Tevatron with ηT→γ+g decay signature, including a complete simulation of signal and background processes. We determined a set of optimal cuts from an analysis of the various kinematical distributions for the signal and backgrounds. As a result we show the exclusion and discovery limits on the ηT mass which could be established at the Tevatron for some technicolor models.
