Tevatron Potential for Technicolor Search with Prompt Photons

We perform a detailed study of the process of single color octet isoscalar $\eta_T$ production at the Tevatron with $\eta_T \to \gamma + g$ 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 $\eta_T$ mass which could be established at the Tevatron for some technicolor models.
