摘要：

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