“…The data for the 12 C-AgBr [13] and 24 Mg-AgBr [14] interactions were obtained by exposing NIKFI BR2 emulsion plates at 4.5 AGeV. The data for the 28 Si-AgBr interactions were obtained from Illford G5 emulsion stacks exposed to an 28 Si beam of energy 14.5 AGeV from the alternating gradient synchrotron (AGS) at Brookhaven National Laboratory (BNL) [15].…”

The search for genuine two-particle dynamical correlations among the target evaporated slow particles in 12 CAgBr and 24 Mg-AgBr interactions at 4.5 AGeV and 28 Si-AgBr interactions at 14.5 AGeV in the emission angle space has been carried out using the method of normalized factorial cumulant moments. The analysis reveals the presence of genuine two-particle dynamical correlations among the target fragments in 12 C-AgBr, 24 Mg-AgBr, and 28 Si-AgBr interactions. The correlations among the target evaporated slow particles are found to decrease with an increase in mass and energy of the projectile beam.

L'analyse révèle de vraies corrélations dynamiques à deux particules dans les fragments de cible des réactions 12 C-AgBr et 24 Mg-AgBr et 28 Si-AgBr. Nous observons que ces corrélations diminuent avec l'augmentation de la masse et de l'énergie du projectile. [Traduit par la Rédaction]

“…The emission angles of black (b), grey (g) and shower (s) track particles for both 'hot' and 'cold' group of events were measured as described in [7]. Table 1 shows the average forward and backward multiplicity for pions and protons, forward-backward ratio and asymmetry parameter for pions and protons, both for 'hot' and 'cold' group of events.…”

A comparison of transverse momentum (Pr) distribution of the alpha particles emitted as projectile fragments from 12C-emulsion interaction at 4.5 A GeV/c with double Maxwell-Boltzmann distribution yields two temperatures in the projectile fragmentation region, i.e., 10 MeV and 40 MeV with different reaction mechanisms, thereby giving rise to two classes of events. This work presents a detailed study of the multiplicity characteristics for pions and protons emitted in both forward and backward hemispheres in these two classes of events. The results show some interesting features in these two classes. 25.70. PACS:

“…Some experimental studies [46][47][48][49][50][51][52][53] were done in order to investigate the multiplicity correlations of the type n c (n i ) in the heavy-ion interactions, where n i = n s , n g , n b , n h , over a wide range of incident energy for different projectiles. The behavior of the compound multiplicity correlation with various secondary particle multiplicities was not widely studied and was limited to few projectiles.…”

In the present paper, some results on the correlations of the nucleus-nucleus interactions, at high energy, between different particle multiplicities are reported. The correlations between the multiplicities of the different charged particles emitted in the interactions of 22 Ne and 28 Si nuclei with emulsion at (4.1-4.5)A GeV/c have been studied. The correlations of the compound multiplicity nc, defined as the sum of both numbers of the shower particles ns and grey particles ng, have been investigated. The experimental data have been compared with the corresponding theoretical ones, calculated according to the modified cascade evaporation model (MCEM). An agreement has already been fairly obtained between the experimental values and the calculated ones. The dependence of the average compound multiplicity, on the numbers of shower, grey, black and heavy particles is obvious and the values of the slope have been found to be independent of the projectile nucleus. On the other hand, the variation of the average shower, grey, black and heavy particles is found to increase linearly with the compound particles. A strong correlation has been observed between the number of produced shower particles and the number of compound particles. Moreover, the value of the average compound multiplicity is found to increase with the increase of the projectile mass. Finally, an attempt has also been made to study the scaling of the compound multiplicity distribution showing that the compound multiplicity distribution is nearly consistent with the KNO scaling behavior.
