A Preliminary Study of the Structure of b anti-bg Events Using
The structure of three-jet b anti-bg events has been studied
using hadronic Z0 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 anti-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
k. We measure k consistent with zero and set limits on its value.
