“…The correction factors U q have also been computed using the Herwig event sample. For both Jetset and Herwig MC generators, the correction factor tends to be less than unity and rises with order q as has been observed earlier [9,10,12]. The difference between the X q quantities calculated with the Jetset and Herwig generated samples has been used in the estimation of the systematic uncertainties.…”

This form has been suggested in [16] to take into account the bias arising from the assumption of infinite statistics in the normalization calculation [3,17] and affects the moments, particularly those computed with small bins.…”

“…This analysis uses more than four million multihadronic events recorded by the OPAL detector at the LEP collider with √ s ≈ m Z 0 . This data sample is much larger than that used in OPAL's previous publication [9], and in other e + e − investigations carried out at the Z 0 peak [10][11][12][13][14] and at lower energies [13,15]. The statistical precision of this data sample allows us to extend the former intermittency analysis [9] to a multidimensional one with the possibility to reach high-order fluctuations at very small bins.…”

Abstract.A multidimensional study of local multiplicity fluctuations and multiparticle correlations of hadrons produced in Z 0 decays is performed. The study is based on the data sample of more than 4×106 events recorded with the OPAL detector at LEP. The fluctuations and correlations are analysed in terms of the normalized scaled factorial moments and cumulants up to the fifth order. The moments are observed to have intermittency-like behaviour, which is found to be more pronounced with increasing dimension. The large data sample allows for the first time a study of the factorial cumulants in e + e − annihilation. The analysis of the cumulants shows the existence of genuine multiparticle correlations with a strong intermittency rise up to higher orders. These correlations are found to be stronger in higher dimensions. The decomposition of the factorial moments into lower-order correlations shows that the dynamical fluctuations have important contributions from genuine many-particle correlations. The Monte Carlo models Jetset 7.4 and Herwig 5.9 are found to reproduce the trend of the measured moments and cumulants but they underestimate the magnitudes. The results are found to be consistent with QCD jet formation dynamics, although additional contributions from other mechanisms cannot be excluded. 240The OPAL Collaboration: Intermittency and correlations in hadronic Z 0 decays
