Angular multiplicity fluctuations in hadronic Z decays and comparison to QCD models and analytical calculations

Document type: Articulo

Abstract

Local multiplicity fluctuations in angular phase space intervals are studied using factorial moments measured in hadronic events at √s≃91.2 GeV, 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.
