Abstract
Using recent DO data on the dijet mass spectrum, we present a limit on flav or-universal colorons. At 95% CL we find M-c/cot theta > 837 GeV. We discus s the implications of this limit for models of quark compositeness, non-sta ndard gluon interactions, and dynamical electroweak symmetry breaking. In a ddition, we place a lower bound Lambda(A8) > 2.1 TeV on the scale of color- octet axial-vector contact interactions among quarks which could arise in m odels of quark compositeness.
