摘要

One of the most important methods for comprehending the fundamental dynamics of high energy nuclear interactions is the investigation of multiparticle correlation. In this study two- and three-particle short-range pseudorapidity ( $\eta $ $η$ ) correlations in $^{84}Kr$ $^{84} K r$ -Em interaction at 1 A GeV are investigated and also examine whether they are energy and mass independent. The analysis is performed using two particle normalized correlation functions ( $R_{2}$ $R_{2}$ ) and three particle normalised correlation function ( $R_{3}$ $R_{3}$ ) in order to examine the underlying dynamics of multiparticle production and the possible clustering behavior of emitted particles. Cumulative shower formation is responsible for the high two-particle short-range $\eta $ $η$ correlation seen in the reverse direction in the target rest frame. Additionally, an analysis of the cumulative $\eta $ $η$ gap distribution is conducted, and the associated cluster features are presented.
