Measurement of observables sensitive to coherence effects in hadronic Z decays with the OPAL detector at LEP

Nadine Fischer, Stefan Gieseke, Stefan Kluth +3

A study of QCD coherence is presented based on a sample of about 397000 $e^{+}{e}^{-}$ hadronic annihilation events collected at $\sqrt{s}=91$ GeV with the OPAL detector at LEP. The stud…
