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.

“…We [7] have also studied KNO scaling for pion-nucleus interactions at 17.2, 50, 200, 300 and 340 GeV in the case of relativistic charged shower particles and tried to fit the function given by Buras et al We also took the value of  as zero. The values of the parameters obtained by us are A=1.50±0.29, B=-0.007±0.03, C=0.17±0.13 and D=-0.95±0.13 with  2 /dof=0.64.…”

“…During the last many years, the work on high energy experiments was carried out by several workers [1][2][3][4][5][6][7][8] mostly for shower particles which are fast moving charged particles or we can say that relativistic charged particles in hadron-nucleus (hA) and nucleus-nucleus (AA) collisions. The investigation of hA collisions is fundamental for understanding the nature of the interaction process.…”

“…The tracks with g*<1.4, 1.4≤g*≤10 and g*>10 were named as shower, grey and black tracks respectively. Other details may be found in our earlier publications [7][8][9][10][11][12].…”

“…When grey and black particles are taken together, they are called as heavy tracks/particles and their number is written by N h (=N g +N b ). Many workers [1][2][3][4][5][6][7][8][9][10][11][12] have studied nuclear interactions using this technique.…”
