Heavy Quark Production in Z0 Decays


We present studies of 3-jet final states from hadronic Z0 decays recorded by the SLD experiment. A comparison of the strong couplings of light, c, and b quarks is made using 3-jet rates. We have performed a detailed study of e+e---> b anti-bg final states, in which the quark, antiquark, and gluon jets are identified. The gluon energy spectrum, measured over the full kinematic range, is consistent with the predictions of QCD, and we derive a limit on an anomalous chromomagnetic bbg coupling. We measure the parity violation in Z0 decays into b anti-bg to be consistent with the predictions of electroweak theory and QCD, and perform new tests of T- and CP-conservation at the bbg vertex.

The PDF version of this document was distilled from a PostScript file most likely created from LaTeX source which used Type 3 fonts. The resultant PDF may be unreadable on the screen at the default viewing magnification (fonts will appear bitmapped, jagged), though the type will be legible at higher magnifications.

Despite the cosmetic problems resulting from the use Type 3 fonts in the original source file, such PDF files print without problems; likewise, the onscreen text is searchable and selectable.
