DOWNLOAD EBOOKThe structure of three-jet b[bar b]g events has been studied using hadronic Z[sup 0] decays recorded in the SLD experiment at SLAC. Three-jet final states were selected and the CCD-based vertex detector was used to identify two of the jets as a b or[bar b]. The distributions of the gluon energy and polar angle with respect to the electron beam were examined and were compared with perturbative QCD predictions. These distributions are potentially sensitive to an anomalous b chromomagnetic moment[kappa]. The authors measure[kappa] consistent with zero and set limits on its value.
