摘要：

Using recent DO data on the dijet mass spectrum, we present a limit on flavor-universal colorons. At 95% CL we find M-c/cot theta > 837 GeV. We discuss the implications of this limit for models of quark compositeness, non-standard gluon interactions, and dynamical electroweak symmetry breaking. In addition, 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 models of quark compositeness.
