Abstract
The temporal fluctuations of produced hadron density in heavy ion collisions, modelled by 2D Ising model at temperatures and below, are studied through a recently developed wavelet based fluctuation analysis method. At , long-range correlated multifractal behavior, matching with the recently observed Hurst exponent , is found. Below uncorrelated monofractal behavior is seen. The correlation behavior compares well with the results obtained from continuous wavelet based average wavelet co-efficient method, as well as with Fourier power spectral analysis.
