Abstract

Local multiplicity fluctuations in angular phase space intervals are studied using factorial moments measured in hadronic events at root s similar or equal to 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, (C) 1998 Elsevier Science B.V.
