Abstract：
A method of n-particle transverse correlation function for the study of collective flow is proposed,which extends both the study of n-particle azimuthal correlations and the estimation of collectivity to the study including the magnitudes as well as the azimuthal angles for all the n-particle transverse momentum vectors.This method is more sensitive to the collectivity of collective flow than the method based on multi-particle azimuthal correlations.Using the new method,n-particle transverse correlations are analyzed for collisions of 1.2A GeV Ar+KC1 in the Bevalac streamer chamber,and the results have been compared with a Monte-Carlo simulation,which show that the collectivity for this experiment is between 85% and 95%.
