Two-particle rapidity correlations between relativistic particles in central collisions of $$^{197}$$ 197 Au nuclei in emulsion at 11.6 A GeV/c

The statistical event-by-event analysis of inelastic interactions of 16 O and 32 S nuclei in emulsion at 60 A GeV/c and 200 A GeV/c reveals the existence of groups of high multiplicity events belonging to very central nuclear interactions with Gaussian pseudorapidity distributions for produced particles as suggested by the original hydrodynamic-tube model. Characteristics of these events are presented. The experimental observations are interpreted as a result of quark-gluon plasma formation in the course of central nuclear interactions.

“…High-energy hadron-nucleus (hA) and nucleus-nucleus (AA) collisions have been investigated extensively by various workers [1][2][3][4][5][6][7][8][9][10][11][12][13][14] in the past. AA collisions may be explained as the superposition of many hA interactions which requires a detailed description of hadronic collisions.…”

The present study is based on the interactions caused by 340-GeV negative pions with emulsion nuclei. The main aim of this paper is to investigate some aspects of central collision events. Thus, the events in which the total number of charged shower particles is greater than or equal to twenty eight (Ns ≥ 28) were chosen for the analysis. They are not exactly central collision events, but may be considered as pseudo-central collision events. The angular characteristics of relativistic charged secondaries have been studied in terms of pseudo-rapidity, and bimodality is found to be absent in the distributions. The mean pseudo-rapidity seems to be independent of grey and heavy particle multiplicities, which indicates its independence with number of collisions. Finally, the correlation between different particle multiplicities in this paper is discussed.
