Shape studies of quark jets versus gluon jets at s=10 GeV
Using date from e+e− annihilation into hadrons taken on the Υ(1S) and continuum, we are able to compare event properties of three-gluon (ggg) and quark-antiquark (q¯q) decays. By tagging radiative decays of the Υ(3S) to the χ′b states, we can make comparisons of the χ′b event shapes with continuum a...

| Summary: | Using date from e+e− annihilation into hadrons taken on the Υ(1S) and continuum, we are able to compare event properties of three-gluon (ggg) and quark-antiquark (q¯q) decays. By tagging radiative decays of the Υ(3S) to the χ′b states, we can make comparisons of the χ′b event shapes with continuum and ggg decays of the Υ(1S). Contrary to the notion that two-gluon (gg) events are globally very similar to q¯q jets, we infer from a study of the χ′b(J=0 or 2) states that gg event shapes more closely resemble ggg decays of the Υ(1S), whereas q¯qg decays of the χ′b(J=1) state more closely resemble q¯q continuum events in their decay characteristics. |
