TECHNICOLOR ENHANCEMENT OF T(T)OVER-BAR PRODUCTION AT TEV COLLIDERS

It is shown that a technicolor theory containing a color-octet technipion, usually denoted by P8(0'), will give rise to an enhancement of ttBAR production at the Fermilab Tevatron, the CERN Large Hadron Collider (LHC), and the Superconducting Super Collider (SSC), via the process gg --> P80' --> ttBAR. The relevant cross sections are computed taking into account the large lower bound on the top mass coming from the "top-quark search" experiments at the CERN e+e- collider LEP and the Collider Detector at Fermilab. At the LHC and SSC, the signal is found to be comparable to the QCD background, making the process quite accessible.
