We present a calculation of the cross section for the process p pbar -> Zt' -> t tbar, the production of a Topcolor Z' with subsequent decay to top quark pairs in proton anti-proton collisions at 1.8 TeV. Variations of the cross section with varying assumptions about the model, the resonance width, the parton distributions and the renormalization scale are presented.

We present a calculation of the cross section for the process p pbar -> Zt' -> t tbar, the production of a Topcolor Z' with subsequent decay to top quark pairs in proton anti-proton collisions at 1.8 TeV. Variations of the cross section with varying assumptions about the model, the resonance width, the parton distributions and the renormalization scale are presented.

These calculations update the results presented in Ref. [ref] for the Tevatron, by both fixing an error in the reported width of the leptophobic topcolor $Z'$, and using $m_t=172.5$ GeV/c$^2$ and CTEQ6L parton distributions in an improved calculation procedure.

The predicted and observed upper limits at 95% CL are shown in Fig. [ref], together with the theoretical prediction for the cross section as a function of mass in the leptophobic $Z'$ model (with $Γ_Z'=0.012 M_Z'$) [ref] .

Figure [ref] and Table [ref] display the resulting limits on $σB$ compared to the limits expected in the absence of a narrow $tt̅$ resonance and to the predicted NLO production cross section of a topcolor $Z'$ boson [ref] as a function of the resonance mass.

Recent discussions in the literature have addressed the possibility of using $t t̅$ production at the Tevatron for putting `direct' constraints [ref] on the Kaluza Klein(KK) gluons of the bulk Randall-Sundrum Model, using their large coupling to the $t t̅$ pairs to probe the same at the LHC through use of $t$ polarisation, in $t t̅$ production [ref] , as well as using spin-spin correlations in $t t̅$ production via KK excitations of the graviton [ref] . $t t̅$ pair production at the Tevatron through a $Z'_t$ in various versions of Topcolor models has also been discussed [ref] .
