Ring like correlation in relativistic heavy ion collision: an experimental probe using continuous wavelet transform approach

TL;DR

This paper applies continuous wavelet transform to analyze pseudo-rapidity distributions in heavy ion collisions, aiming to detect ring-like correlations indicative of Cherenkov gluons or Mach shock waves, and compares experimental data with simulations.

Contribution

It introduces a wavelet-based multiscale analysis method to identify ring-like correlations in heavy ion collision data, distinguishing between different physical mechanisms.

Findings

Detected ring-like correlations in experimental data.

Simulation results did not reproduce the experimental correlations.

Wavelet analysis effectively identifies features related to Cherenkov gluons or Mach shocks.

Abstract

Continuous wavelet transform approach has been applied to the pseudo-rapidity distribution of shower particles produced in 16O-AgBr interactions at 60 AGeV and 32S-AgBr interactions at 200 AgeV. Multiscale analysis of wavelet pseudo-rapidity spectra has been performed in order to find out the presence of ring-like correlation, which could be either due to production of Cherenkov gluons or due to propagation of Mach Shock wave through excited nuclear matter. This approach fulfils the basic requirement of both effects that they lead to an overabundance of considered particles at some typical pseudo-rapidities. Comparison of experimental results with that obtained from analyzing events generated by FRITIOF code are not reproduced.
