We present numerical calculations of the production cross section of a heavy Z′ resonance in hadron–hadron collisions with subsequent decay into top–antitop pairs. In particular, we consider the leptophobic topcolor Z′ discussed under Model IV of hep-ph/9911288, which has predicted cross sections large enough to be experimentally accessible at the Fermilab Tevatron and the Large Hadron Collider at CERN. This article presents an updated calculation valid for the Tevatron and all proposed LHC collision energies. Cross sections are presented for various Z′ widths, in collisions at , and in pp collisions at .
