Angular multiplicity fluctuations in hadronic Z decays and comparison to QCD models and analytical calculations
Abstract
Local multiplicity fluctuations in angular phase space intervals are studied using factorial moments measured in hadronic events at sā91.2GeV, which were collected by the L3 detector at LEP. Parton shower Monte Carlo programs agree well with the data. On the other hand, first-order QCD calculations in the Double Leading Log Approximation and the Modified Leading Log Approximation are found to deviate significantly from the data.
