Wavelet Analysis of Produced Pions in 24Mg-Ag/Br Interactions at 4.5 A GeV/c

Angular spectra of the unusual superspiky events produced in 24 Mg-Ag/Br interactions at 4.5 A GeV/c are analyzed by the method of continuous wavelet transform in different scale for the ring-like structures which could indicate either the production of Cherenkov gluons or the occurrence of Mach sho...

Description
Summary:Angular spectra of the unusual superspiky events produced in 24 Mg-Ag/Br interactions at 4.5 A GeV/c are analyzed by the method of continuous wavelet transform in different scale for the ring-like structures which could indicate either the production of Cherenkov gluons or the occurrence of Mach shock waves in excited nuclear matter. The analysis is based on the assumption that the presence of abovementioned effects would be manifested by excess of particles at some characteristic pseudorapidities. The irregularities are revealed in the wavelet pseudorapidity spectra in the scale pseudorapidity region. These irregularities are interpreted as the preferred pseudorapidities of groups of emitted particles.
