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 (qq̅ ) decays. By tagging radiative decays of the ϒ(3S) to the χb′ states, we can make comparisons of the χb′ 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 qq̅ jets, we infer from a study of the χb′(J=0 or 2) states that gg event shapes more closely resemble ggg decays of the ϒ(1S), whereas qq̅ g decays of the χb′(J=1) state more closely resemble qq̅ continuum events in their decay characteristics.
