Shape studies of quark jets versus gluon jets ats=10GeV

Using date from $e^{+}{e}^{-}$ annihilation into hadrons taken on the $\Upsilon \mathrm{}\left(1S\right)\mathrm{}$ and continuum, we are able to compare event properties of three-gluon ($\mathrm{ggg}$) and quark-antiquark ($q\overline{q}$) decays. By tagging radiative decays of the $\Upsilon \mathrm{}\left(3S\right)\mathrm{}$ to the ${\chi }_b^{\prime }$ states, we can make comparisons of the ${\chi }_b^{\prime }$ event shapes with continuum and $\mathrm{ggg}$ decays of the $\Upsilon \mathrm{}\left(1S\right)\mathrm{}$. Contrary to the notion that two-gluon ($\mathrm{gg}$) events are globally very similar to $q\overline{q}$ jets, we infer from a study of the ${\chi }_b^{\prime }(J=0\mathrm{} or 2)$ states that gg event shapes more closely resemble $\mathrm{ggg}$ decays of the $\Upsilon \mathrm{}\left(1S\right)\mathrm{}$, whereas $q\overline{q}g$ decays of the ${\chi }_b^{\prime }\mathrm{}(J=1\mathrm{})\mathrm{}$ state more closely resemble $q\overline{q}$ continuum events in their decay characteristics.
