Particle spectrum in gluon jets produced in e+e- annihilations at s around 58 GeV

Inclusive momentum spectra of charged particles in three-fold symmetric three-jet (qqg) and two-jet +\ensuremath{\gamma}(qq\ensuremath{\gamma}) events taken from ${\mathit{e}}^{+}$${\mathit{e}}^{\mathrm{\ensuremath{-}}}$ annihilation at center-of-mass energy of 58 GeV were compared. The spectrum of gluon jets was found to be significantly softer than that of quark jets with the same energy and topology.
