“…may be found elsewhere. [48][49][50][51] It should be mentioned that conventional emulsion technique have two main advantages over the other detectors: i) its 4π solid angle coverage and ii) data are free from biases due to full phase space acceptance. The details of the event samples used in the present study are listed in Table 1.…”

beam momenta i.e., p-H, p-CNO, p-AgBr at 200A GeV/c and 16 O-AgBr collisions at 14.6, 60 and 200A GeV/c. Further, multiplicity fluctuations are quantified in terms of intensive quantity, the scaled variances ω and the strongly intensive quantity Σ F B derived from the charged particle multiplicity and the width of the multiplicity distribution. Strongly intensive quantity Σ F B is a quantity of great significance to extract information about short and long-range multiplicity correlations. Furthermore, the collision centrality and centrality bin width dependent behavior of the multiplicity fluctuation have been examined in the framework of Lund Monte Carlo based FRITIOF model. Results based on the fluctuation analysis carried out in the present study are interpreted in terms of dynamics of collision process and the possibility of related QCD phase transition.

“…The main aim of the present study is to search for the rare events exhibiting some unusual behaviour from a data sample with large number of events. The analyses of individual collision events at SPS and RHIC energies have been argued to statistically reliable as the multiplicities of these events would be high enough and the statistical fluctuations may be treated as under control [15][16][17][18][19][20][21][22]. Moreover, from the study of such events with strong fluctuations, information about the dominance of dynamical components of fluctuations over the statistical ones can be extracted, which, in turn, would provide more insight into the underlying dynamics of high multiplicity events [23,24].…”

“…This not only reduces the charged particle multiplicity but might also distort some of the event characteristics, like particle density fluctuations. Furthermore, to test whether the fluctuations are arising due to nonstatistical reasons, the findings are compared with the reference distributions obtained by event mixing technique [15,16,32].…”

Analysis of high multiplicity events produced in 158A GeV/c 208 Pb-208 Pb collisions is carried out to study the event-by-event fluctuations. The findings reveal that the method of scaled factorial moments can be used to identify the events having densely populated narrow phase space bins. A few events sorted out by adopting this approach are individually analyzed. It is observed that these events do exhibit large fluctuations in their pseudorapidity, , and azimuthal angle, , distributions arising due to some dynamical reasons. Two-particle Δ -Δ correlation study applied to these events too indicates that some complex two-dimensional structure of significantly high magnitude is present in these events which might have some dynamical origin. The findings reveal that the method of scaled factorial moments may be used as an effective triggering for events with large dynamical fluctuations.
