Probing multi-particle bunching from intermittency analysis in relativistic heavy-ion collisions

Year: 2024

Type: article

Abstract: It has been demonstrated that factorial moments analysis in dependence on the size of phase-space cells (when the latter is decreased but is still considerably large) exhibits sensitivity to particle bunching within a system situated in the two-dimensional cell. Based on recent findings concerning fluctuations in charge particle density observed in central Au + Au collisions at various energies ranging from s N N = 7.7 to 200 GeV at RHIC/STAR, it is proposed that analyzing factorial moments in relativistic heavy-ion collisions could serve as a method to investigate density fluctuations linked to correlation phenomena. Our understanding of particle production mechanisms may be enriched by using factorial moments analysis to gain new information contained in them that was initiated four decades ago from observation of “spike” phenomena.
