Various aspects of the simple phenomenological model, the grand combinational model (GCM), proposed earlier for the systematic description of the center-of-mass (cm) rapidity distributions of different particles produced in high energy heavy ion collisions, were analyzed. The values of GCM parameters were extracted from fitting the cm rapidity distributions of the negative pions in 12 C+ 12 C collisions at √ snn = 3.14 GeV both in the experiment and using Modified FRITIOF Model. The GCM parameters extracted for the central 12 C+ 12 C collisions were compared with those obtained in central Pb+Pb collisions at super proton synchrotron (SPS) and alternating gradient synchrotron (AGS) energies between √ snn = 6.3 GeV and √ snn = 12.3 GeV and in central Au+Au collisions at Relativistic heavy ion collider (RHIC) energies between √ snn = 19.6 GeV and √ snn = 200 GeV. The plausible physical interpretations for the GCM parameters were given. The initial assumption that the parameter β of GCM should be zero for symmetric systems with identical colliding nuclei was validated. The parameter γ of GCM was deduced to follow an approximate asymptotic behavior (γ → 0 as √ snn → ∞) at very large cm energies, and γ ∼ = 0 could possibly be related to complete dehadronization of the whole collision system, along with attaining its maximum possible energy density, in central collisions of identical nuclei.

“…Recently, De Bhattacharyya parametrization is being extensively applied to interpret the measured data on the various aspects 2,4-7 of the particle-nucleus and nucleus-nucleus interactions at high energies. Recently Hwa et al 13 also made use of this sort of relationship in a somewhat different context. The underlying physics implications of this parametrization stem mainly from the expression (2) which could be identified as a clear mechanism for switch-over of the results obtained for nucleon-nucleon (P P ) collision to those for nucleus-nucleus interactions at high energies in a direct and straightforward manner.…”

BRAHMS collaboration 1 had studied in the recent past some properties of the detected identified charged hadrons in gold-gold collisions at √ s N N = 200 GeV as a function of p T and collision-centrality at two rapidity values. The reported characteristics, which are not offshoots of any specific model whatsoever, and are measured in a model-independent manner, would be dealt with in the light of a phenomenological framework named combinational approach.

“…4 A system undergoing a second-order phase transition is envisaged to exhibit large fluctuations and long-range correlations. 6 If the symmetry of the quark system created in a heavy-ion collisions is such that the quark-hadron phase transition is of the second-order then large fluctuations are expected in the multiplicity of hadrons not only from event-to -event but also from one region to the other in the geometrical space in which emission of hadrons takes place. 6 Such local hadron density fluctuations would result in the formation of spatial patterns involving cluster of hadrons and regions of no hadrons between adjacent clusters.…”

Event-by-event (ebe) fluctuations of hadronic patterns are investigated in terms of voids by analyzing the experimental data on 4.5, 14.5 and 60 A GeV/c 16 O-AgBr collisions. The findings are compared with the predictions of a multi-phase transport AMPT model. Dependence of voids on phase space bin width is examined in terms of two lowest moments of ebe fluctuations of voids, Gq and Sq. The findings reveal that scaling exponent estimated from the observed power-law behavior of the voids may be used to characterize the various properties of hadronic phase transition. The results also rule out occurrence of second-order quark-hadron phase transition at the projectile energies considered.
