Comparison of quark and gluon jets produced in high-energye+e−annihilations

Three-jet events produced in {ital e}{sup +}e{sup {minus}} annihilations are used to provide comparisons between quark and gluon jets. Differences between quark-induced and gluon-induced jets are observed. Quark jets tend to have a more tightly collimated structure than gluon jets, which is reflected in the concentration of a larger fraction of the jet's energy near the jet axis.
