“…This signifies that the particle production mechanism is partly coherent and partly chaotic in nature. It should be mentioned here that in all of the previous reports [15,[18][19][20][21][22] of void probability scaling, experimental points lie in between the two lines representing the minimal model and the NBD model. So it may be commented that in 22 Ne, 28 Si, 16 O and 32 S projectiles with AgBr and CNO targets at Dubna energy.…”

“…In high energy physics there is growing activity in both experimental and theoretical studies investigating the occurrence of densely populated and empty phase cells caused by dynamic fluctuations. Several authors [18][19][20][21][22] investigating the rap-gap probability P 0 ( η) found a scaling behavior predicted by the hierarchical models in the central rapidity domains in high energy nucleus-nucleus collisions. All of the analyses [18][19][20][21][22] provided a sensitive test for the linked-pair approximation of the higher-order cumulant correlations.…”

A detailed study of clan model parameters and their target dependence has been carried out in the light of void probability scaling for heavy (AgBr) and light (CNO) groups of targets present in the nuclear emulsion using 22 Ne (at an incident momentum of 4.1 GeV/c), 28 Si (at an incident momentum of 4.5 GeV/c), 16 O (at an incident momentum of 4.5 GeV/c) and 32 S (at an incident momentum of 4.5 GeV/c) projectiles. The variation of scaled rapgap probability with the single moment combination has been studied for all of the interactions. The experimental points are found to lie approximately on the NBD curve for all of the interactions, indicating a scaling behavior. According to the two-source model of particle production, in the case of 32 S-AgBr interactions at 4.5 GeV/c, the pion production mechanism has been found to be almost chaotic. On the contrary, for all of the other interactions at 4.1-4.5 GeV/c, pion production is predominantly chaotic. Average clan multiplicities (N) for all of the interactions are found to increase with the increase in the pseudo-rapidity interval η. The values of N for the AgBr target are larger than those for the CNO target. The average number of particles per clan (n c ) increases initially with the increase in pseudo-rapidity interval. An approximate saturation of the values of n c is observed for 22 Ne and 16 O projectiles around η = 6. With the increase in projectile size, the saturation of n c seems to be wiped out. It can also be observed from the tables that for a particular target the average number of particles per clan (n c ) increases with the increase in the size of the projectile nucleus. A comparison with the results of the SPS data has also been presented.

Abstract. The article focuses on study of clan model parameters and their target dependence in light of void probability scaling for heavy (Ag and Br) and light (C, N and O) groups of targets present in nuclear emulsion detector using 84 Kr 36 at ~1 A GeV. The variation of scaled rapiditygap (rap-gap) probability with single moment combination has been studied. We found that experimental points are lying approximately on the negative binomial distribution (NBD) curve, indicating a scaling behavior. The average clan multiplicities ( ) for interactions, increases with the pseudo-rapidity interval (∆η) was also observed. The values of for AgBr targets are larger than those for CNO target and also average number of particles per clan ( ) increases with increase in pseudo-rapidity interval. We further observed that for a particular target, average number of particles per clan ( ) increases with an increase in the size of projectile nucleus.
