Abstract
We present the first experimental results based on the jet boost algorithm, a technique to select unbiased samples of gluon jets in [Formula Presented] annihilations, i.e. gluon jets free of biases introduced by event selection or jet finding criteria. Our results are derived from hadronic [Formula Presented] decays observed with the OPAL detector at the LEP [Formula Presented] collider at CERN. First, we test the boost algorithm through studies with HERWIG Monte Carlo events and find that it provides accurate measurements of the charged particle multiplicity distributions of unbiased gluon jets for jet energies larger than about 5 GeV, and of the jet particle energy spectra (fragmentation f..
