Limits on Flavor-Universal Colorons

A flavor-universal extension of the strong interactions was recently proposed in response to the apparent excess of high-$E_T$ jets in the inclusive jet spectrum measured at the Tevatron. The color octet of massive gauge bosons (`colorons') that is present in the low-energy spectrum of the model's Higgs phase is studied here. Experimental constraints already imply that the coloron mass must exceed 870-1000 GeV. The import of recent Tevatron data and the prospective input from future experiments are also mentioned.
