This paper presents an analysis on fractality of compound hadrons (pions + protons) and shower particles produced in heavy ion interactions initiated by 12C and 24Mg beams at incident energy 4.5A GeV and 32S beam at incident energy 200A GeV. G-moments analysis in emission angle (cosθ) space reveals multifractality in both compound hadrons and pion emission process. The degree of multifractality has been assessed using the Levy stability index. Moreover this analysis also suggests nonthermal phase transition in multiparticle production for both cases.

This work presents a study on the multiplicity distribution of shower and compound multiplicity (pions + target protons) emitted from 12 C – AgBr and 24 Mg – AgBr interactions at 4.5 AGeV in terms of negative binomial distribution (NBD) and also on the fluctuation pattern of shower and compound multiplicity in the frame work of two-dimensional factorial moment methodology using the concept of Hurst exponent.

We compute the factorial correlators to study the dynamical fluctuations of pions and a combination of pions and protons (compound multiplicity) in 32S-AgBr interactions at 200 A GeV. The study reveals that for both pion and compound multiplicity the correlated moments increase with the decrease in bin-bin separation D, following a power-law, which suggests the self-similarity of multiplicity fluctuation in each case. The results of the analysis also show a consistency with the prediction of α-model for the existence of intermittency in both cases.

This paper presents an investigation of compound hadrons (pions and protons) distribution emitted from 24Mg-AgBr and 12C-AgBr interactions both at 4.5 AGeV and 32S-AgBr interactions at 200 AGeV. The study includes azimuthal correlations (two particle and three particle), azimuthal asymmetry and fractal behaviour. This paper reveals some interesting results.

This paper reports an investigation of two- and three-particle dynamical correlation in multiparticle production processes in terms of compound multiplicity (proton and pion) distributions. The data have been taken from 24Mg–AgBr and 12C–AgBr interactions at 4.5 AGeV. The experimental results are compared with those of Monte Carlo simulated events, assuming an independent emission of the compound multiplicity. The data exhibit strong two- and three-particle correlation in both forward and backward hemispheres in emission angle space for both data sets. PACS Nos.: 25.75–q, 24.60 Ky

This paper reports a detailed study on self-affine behavior of multiplicity fluctuation in the pionization process at relativistic and ultrarelativistic nuclear collisions. The study was performed over a wide range of energy from 2.1–200 AGeV. The data used are 16 O-AgBr interactions at 2.1 AGeV and 60 AGeV, 32 S-AgBr interactions at 200 AGeV, 24 Mg-AgBr , and 12 C-AgBr interactions at 4.5 AGeV. All these data show a clear evidence of self-affine pion production over the entire energy regime.

Different fractal methods (Factorial moment, Takagi moment) have been used for the analysis of fractal behavior of multiparticle production in π-- AgBr interaction at 350 GeV/c of compound multiplicity distribution in emission angle (cos θ) space and azimuthal angle (ϕ) space. The generalized fractal dimensions Dq are determined according to two methods. Results indicate multifractal behavior in compound multiplicity distribution. From the knowledge of Dq, the multifractal specific heat is calculated. Results are compared with the corresponding results of shower multiplicity.

An investigation of non-statistical fluctuation of the compound multiplicity spectrum in 32S–AgBr interactions at 200 AGeV in terms of factorial correlators is presented. It is observed that the correlated moments increase with decrease in bin–bin separation D, following a power law, which suggests the presence of an intermittent nature of self-similar dynamical fluctuation patterns in the compound multiplicity spectrum. The data also support the α model of intermittency.

This paper reports an analysis on fractality using the experimental data of compound multiplicity (pions + target protons) distribution in 24Mg-AgBr interactions at 4.5 AGeV following the method proposed by F. Takagi. Takagi moments have been calculated for 2nd, 3rd, 4th, and 5th order in the emission angle and azimuthal angle space. The results of our study reveal the multi-fractal structure of compound multiplicity distribution.

We present a study of the `compound multiplicity' distribution in terms of scaled factorial moments of orders 2, 3, 4 and 5 in 24Mg-AgBr interactions at 4.5 AGeV. The study reveals a strong signal of the intermittent pattern of fluctuation in the compound multiplicity distribution.
