Wavelet Analyses of High Multiplicity Events

Pseudo-rapidity distributions of high multiplicity JACEE events ( Ca-C, Si-AgBr and G27) and Texas Lone Star (TLS) event are analysed by the wavelet transform method. Using the Daubechies' waveltes, $D_4, D_6, D_8,$ and $ D_{10} $, wavelet spectra of those events are calculated. Two JACEE events are compared with the simulation calculations. We discuss how to distinguish prominent peak from apparent peaks. The wavelet spectrum of Ca-C event seems to resemble that simulated with the Poisson random number distributions. The wavelet spectrum of TLS event shows an oscillatory behavior. It is found that the wavelet spectra of JACEE G27 event are different from those of Arizona group.
