Description
A study of QCD coherence is presented based on a sample of about
397.000 e$^+$e$^-$ hadronic annihilation events collected at
$\sqrt{s}=91$ GeV with the OPAL detector at LEP. The study is based
on four recently proposed observables that are sensitive to coherence
effects in the perturbative regime. The measurement of these
observables is presented, along with a comparison with the predictions
of different parton shower models. The models include both
conventional parton shower models and dipole antenna models.
Different ordering variables are used to investigate their influence
on the predictions.
