Study of the structure of e+e-→bb¯g events and first limits on the anomalous chromomagnetic coupling of the b quark

The structure of e+e-→bb¯g events was studied using Z0 decays recorded in the SLC Large Detector experiment at SLAC. Three-jet final states were selected and the charge-coupled device-based vertex detector was used to identify two of the jets as b or b¯. Distributions of the gluon energy and polar angle were measured over the full kinematic range for the first time, and compared with perturbative QCD predictions. The energy distribution is …
