Abstract
We consider the jet cross sections for gluons coupling to quarks with an anomalous chromomagnetic moment. We then apply this to the deviatio n and bounds from QCD found in the CDF and DO Fermilab data, respectiv ely,to find a range of possible values for the anomalous moments. The quadratic and quartic terms in the anomalous moments can fit to the ri se of a deviation with transverse energy. Since previous analyses have been done on the top quark total cross section, here we assume the sa me moment on all quarks except the top quark and find the range \kappa '\=\kappa/(2m(q))\=1.0+/-0.3 TeV-1 for the CDF data. Assuming the anom alous moment is present only on a charm or bottom quark which is pair produced results in a range \kappa'(b,c)\=3.5+/-1.0 TeV-1. The magnitu des here are compared with anomalous magnetic moments that could accou nt for Rb and found to be in the same general range, as well as not in consistent with CERN LEP and SLD bounds on Delta T-had.
