Anisotropy fluctuation and correlation in central α-clustered 12C+197Au collisions
Abstract
In the framework of a multi-phase transport model, fluctuation and correlation of the azimuthal anisotropies in 12C+197Au collisions at SNN = 200 GeV are explored. Properties of the initial eccentricity and final harmonic flow fluctuation resulted from 12C+197Au collisions with Woods-Saxon configuration and triangular α-clustering configurations of 12C are investigated via scaled variance, skewness and kurtosis. Comparisons are made between results from α-clustered configurations and Woods-Saxon configuration. The triangular flow fluctuation is found to have particular sensitivity in distinguishing triangular α-clustering structure of 12C. Furthermore, correlations between initial eccentricities and final flow harmonics are studied with strong multiplicity dependence observed for the correlation functions.
