FACTORIAL CORRELATION-FUNCTIONS AND PROTON-MULTIPLICITY FLUCTUATIONS IN AZIMUTHAL-ANGLE INTERVALS IN INELASTIC-COLLISIONS OF C-12 WITH PROPANE AND TANTALUM AT A MOMENTUM OF 4.2 GEV C PER NUCLEON/

Correlations between proton-multiplicity fluctuations in small bins of azimuthal angles are studied for inelastic C-C3H8 and C-Ta interactio ns at 4.2 GeV/c per nucleon. Analysis of these fluctuations is based o n the method of factorial correlation functions. Factorial correlation functions increase with decreasing correlation length, irrespective o f the width of azimuthal-angle bins, In the majority of cases, this in crease does not follow a power law. However, these correlation functio ns are independent of the bin size, in accordance with the simple alph a model of intermittency.
